Answers

1. a

Just the same as 18 - 4. If you are adding signed numbers, each positive
will cancel out a negative. Since we have 4 more positives than negatives,
the answer is positive 4. No need for a sign on positive numbers.

2. c.

The width was 7, now 14. The perimeter is now 14 + 14 + 10 + 10 = 48.

3. b.

Calculate 4300 + 350 - 67 - 247 + 150 to get 4486.

4. e.

14% of 2300 is 322. Do .14 x 2300 or 14 x 23.

5. d.

6. b.

Calculate the amount she has budgeted and compare. 0.05 x 2300 or 5
x 23 = 115. 120 is 5 over.

7. d.

Use the figure you got in # 4 and multiply it by 3.

* Test taking hint: why recalculate numbers you already did ? Look
back!

8. a.

We have 22 negatives and 10 positives. That's 12 more negatives, so
-12 is the answer.

9. c.

Other answers are close, but c reduces down exactly.

10. a.

Start at ones you know and compare. You should be able to tell that
b, c, and e are all more than a and d. Then realize 0.06 is 6%, so it is
the least.

11. c.

You need a fraction that reduces to 1/4th. 8/32 = 1/4.

12. c.

Learn 9ths. Each 9th is a repeating decimal. It repeats the number
on top.

1/9 = .11111....

2/9 = .22222....

3/9 = .33333...

And so on. Round as needed. 7/9 = .77777....., so the closest is 0.78.

13. a.

3 feet to a yard, so 4.5 yards = 3 x 4.5 = 13.5 feet. 12 inches to
a foot, so 13.5 feet = 13.5 x 12 = 162 inches.

14. e.

Negative numbers get smaller as the number gets bigger. d can be eliminated
because the 2 values are equal. The inequality signs always points to the
smaller number. Think: Small point, smaller number. Wide side, larger number.

15. e.

9 students are failing out of 36. This reduces to 1/4 or 25%

16. d.

All other choices give false statements shown in the following

a becomes 3 + 3 > 3 + 5 or 6 > 8 which is false.

b becomes -3 > -3 + 3 or -3 > 0 which is false.

c becomes 2 x 3 > 3 x 3 or 6 > 9 which is false.

e becomes 3 - 3 > 3 + 3 or 0 > 9 which is false.

Answer d is 3 + 5 > -6 + 3 or 8 > -3 which is true.

17. c.

2 quarts is half a gallon. 1 gallon is 3.8 liters, so half a gallon
would be 1.9 liters.

18. a.

Multiply 3.4 x 5280 to get 17952.

You could have added 5280 + 5280 + 5280 to get 15840. But you know
it is about a half mile more. Logical choice would be a.

19. b.

Getting rid of a negative is a "positive" thing. So, it is just
like adding the same number. The equation becomes 9 + 8 + 5 = 22.

You could do the positives first, 9 + 5 to get 14. You know you either
add or subtract 8 to get 22 or 6.

Think logically, is 9 - (-8) the same as 9 - 8 ? No! Of course
you logically need to realize that -(-8) = +8

20. a.

All groups go from the 0 to the next 9. It should be obvious which
one is missing.

21. d.

The last row is the total of students in the column. Here it is the
8th grade column. It all adds up to 261.

22. c.

Add all boxes in the 6th grade column that are from 50-59 on up.

This would be 87+24+16+14+4 = 145

23. b.

The total for the column is 310. All other boxes in this column add
to 289. 310 - 289 = 21.

24. c.

We are looking at 2000, the dark line. It appears flat between May
and June.

* You need to realize the first letter of the month is how they are
written at the bottom. The first J stands for January.

25. e.

Look at each month and decide which gap appears largest. April is by
far the largest gap.

26. a.

2000 is the dark line and it should be clear it is about half way between
40000 and 50000. You can always use a corner of your test book to
fold up to get a straight line.

27. b.

Look only at the months listed. Find one where the dark line is below
the shaded line.

August works.

28. d.

At 5 pm the temperature was 8 degrees. (25 - 17). To get to -20, you
need to go 8 degrees to get to 0, then 20 more. Total of 28 degrees.

29. b.

549 divided by 32 is 17 and a little more. We need 1 extra classroom
for that. Total 18 classrooms. Don't worry how your school does it or if
this is the best way.

30. a.

Divide 704 by 11 then multiply by 3.

Or solve the equation 3/11 = x/704. Which number on top of 704 would
reduce to 3/11?

You could work backward and try all answers to get one that works.

31. e.

If there is a line under the inequality sign, it means it is okay for
both sides to be equal as well.

The only number listed that works is 5.

32. e.

Calculate 237 - 56 + 75 - 43 to get 213.

33. b.

Each choice is reasoned through below:

a. We have no idea how many boots are left.

b. We know we started with 67 and now have 60 We CAN assume 7 were
sold.

c. We have no idea how many athletic shoes are left.

d. We cannot assume each customer bought only 1 pair of shoes. Some
may have bought more.

e. We have no idea how many were returned.

34. d.

We don't care whether it is red or green. Either one will do. If this
is confusing, think of the question as being "What are the chances of NOT
taking a yellow ball?" It is the same question. Either way you get 11/20.

35. a.

Her hourly wage is extra information and does not figure into the problem.

Each choice is reasoned through below:

a. If she works at least 8 hours, she will work her minimum of 25 hours.
This is true.

b. She could indeed work 13 hours more.

c. How do we know how many hours she will work on a day?

d. How do we know she will not work on Thursday?

e. How do we know she did not work on Sunday?

36. a.

Calculate as follows:

72 pencils = 6 dozen, 6 x 0.27 = 1.63

20 boxes of crayons = 20 x 0.48 = 9.6

10 sets of markers = 10 x .96 = 9.6

Total = 1.63 + 9.6 + 9.6 = 20.82

37. b.

At 12 noon, Joe has been traveling for 3 hours at an average speed
of 60 mph. Therefore, he has driven 180 miles (3 x 60). Carl catches up
to him at this time, which means Carl has done 180 miles in 2.5 hours.
Divide 180 by 2.5 to get 72. Or you could work backwards and multiply each
answer by 2.5 and see which one gives a value of 180.

a. 2.5 x 60 = 150

b. 2.5 x 72 = 180

c. 2.5 x 65 = 162.5

d. 2.5 x 62 = 155

e. 2.5 x 80 = 200.

38. e.

Raw score is how many answers were correct.

39. c.

National Norm is the average for all students who took the test (nationally).

40. b.

Grade Equivalent is grade level the student tests at. 5.7 means 5th
grade, 7th month. IT IS NOT meant for comparing students to other grades.
It does not mean student can do 5th grade work, nor should be skipped ahead.
The only valid conclusion is above average for a 4th grader. It says nothing
about a student's IQ.

41. a.

Do what is inside the parentheses first. Substituting 77 for F we get
77 - 32 = 45. Then multiply by 5/9.

You can do this many ways.

The easiest way is to multiply 45 x 5, then divide by 9. This would
give 225/9 which is 25.

You could have divided 45 by 9 first, then multiplied by 5.

You could have also noted that 5/9 is about .56, so multiply 45 by
.56 to get 25.2. Closest answer would be 25.

42. e.

Here we need to multiply (9/5) x 15. (On most tests the 9/5 would not
be in parentheses)

9/5 = 1.8, so multiply 15 b 1.8 to get 27. Then add 32 to get 59.

*You do not add 15 + 32 first. These are not in parentheses! You must
multiply first.

Another way to multiply 9/5 x 15 would be (9 x 15)/5.

Another way to multiply 9/5 x 15 would be to divide 15 by 5, then multiply
by 9.

In all cases you get 27.

43. c.

Compare the increase to the original price. 3/40. This is the percent
increase.

3/40 means divide 3 by 40 to get 0.075 or 7.5%

You could also reason your way through it as follows:

We are looking at 3 out of 40.

10% of 40 = 4, so we know it is less than 10%

5% of 40 = 2, so we know it is more than 5%

This now eliminates answer a.

1% of 40 = .4, so 6% = 2.4, 7 % = 2.4 + .4 = 2.8, 8% = 2.8 + .4 = 3.2

But now we have gone too far. It is between 7% and 8%. The only choice
is c.

44. d.

You are looking for a number that when you take 1/3 of it and add it
to 8 you get 17.

The only number when added to 8 to give 17 is 9.

But the answer cannot be 9 because we are looking at a third of a number
to be 9.

9 is 1/3 of 27. So, x = 27.

You could work backwards, checking each answer.

However, because we are finding a third, the answer must be divisible
by 3.

That eliminates answers a,b, and e.

9 looks attractive because 9 + 8 = 17.

But (1/3)9 + 8 = 3 + 8 = 11 and

(1/3)27 + 8 = 9 + 8 = 17. 27 is the only one that works.

45. b.

Assume all angles are right angles.

We know we have 12 + 8 + 6 + 10 = 36. But we are missing 2 sides.

The bottom side will be 8 + 6 = 14 (Look at the top sides. See how
they correspond to the bottom length?)

The missing side between the 8 and 6 must be 2. (Look at the left side.
It is 12. Look at the right side. It is 10. The missing length must be
added to 10 to get 12. So, it has to be 2)

Perimeter = 36 + 14 + 2 = 52.

46. c.

5 of the 30 marbles are green. The fraction 5/30 reduces to 1/6.

47. b.

We need 2 numbers to total up to 54. Many combinations work, but only
one where 1 number is 12 more than the other one. Work backward. Remember,
we are looking for the smaller number, not the larger.

Reason through the answers as follows:

a. If 32 is the smaller, then 44 is the larger. But 44 + 32 = 76, not
54.

b. If 21 is the smaller, then 33 is the larger. And 33 + 21 = 54.

c. If 52 were the smaller, then 64 is the larger. Way too big.

d. Same as c.

e. same as c.

48. b.

You need to think of both values in terms of fractions and decimals.

1/3 is about .33, and 0.6 is 6/10.

The range is between 1/3(.33) and 6/10(.6)

Look at each answer:

a. 1/5 = .2

b. 4/10 = .4

c. .05 = 5/100

d. 1/4 = .25

e. 0.7 = 7/10

The only answer that fits between the given values is b, 0.4.

49. d.

Glance through the answers and see if you can eliminate some right
off.

All are more than 1/2 except e, so eliminate e.

7/10 is .7 or 70%. This should let you see that it is bigger than a
and b.

We now need to compare 7/10 to 9/15.

To compare 2 fractions, multiply the denominator of one by the numerator
of the other.

Multiply bottom to top, placing the product above that fraction that
you multiplied the top by.

Look at the diagram. 10 x 9 is 90, put 90 above the 9. 15 x 7 = 105,
put 105 above the 7.

The side that now has the larger number is the larger fraction. Since
105 is larger than 90, it is on the side of the larger fraction. So, the
larger fraction is 7/10. Use this technique to compare any fractions.

50. b.

Reason out each answer as follows:

a. He could work 29 more hours. but does not have to. The word
"must" implies he has too.

b. 16 more would give him 25. Yes, he could work 25.

c. He could indeed work 20 hours more.

d. See answer c.

e. He could work 9 more hours, but does not have too.
