2) Represent the ratio 7 : 18 in two other ways

The ratio 7:18 can be represented in two other ways as 14:36 and 21:54. This is because the ratio can be multiplied or divided by the same non-zero number to get equivalent ratios. In this case, multiplying 7 and 18 by 2 gives 14 and 36, and multiplying by 3 gives 21 and 54.

3) What is the unit rate for travelling 212 km in 6 hours?

0.03 km/h

35.33 km/h

30.29 km/h

42.4 km/h

Remember, you want to get a denominator of 1 for unit rate. 212 km / 6 hours. Divide by 6.

Explanation

Remember, you want to get a denominator of 1 for unit rate. 212 km / 6 hours. Divide by 6.

4) Which ratio is equal to 100 : 20?

10 : 2

80 : 2

2 : 10

10 : 14

The ratio 10:2 is equal to 100:20 because both ratios can be simplified to 5:1. This means that for every 5 units in the first term of the ratio, there is 1 unit in the second term. So, if there are 100 units in the first term, there will be 20 units in the second term, resulting in the ratio 100:20.

7) Leroy can lay 144 bricks in 3 hours. At this rate, how many bricks can he lay in 7 hours?

48

336

1,008

250

Leroy can lay 144 bricks in 3 hours, which means he can lay 48 bricks in 1 hour (144 divided by 3). To find out how many bricks he can lay in 7 hours, we can multiply the number of bricks he can lay in 1 hour (48) by the number of hours (7), which gives us 336 bricks. Therefore, the correct answer is 336.

Explanation

Leroy can lay 144 bricks in 3 hours, which means he can lay 48 bricks in 1 hour (144 divided by 3). To find out how many bricks he can lay in 7 hours, we can multiply the number of bricks he can lay in 1 hour (48) by the number of hours (7), which gives us 336 bricks. Therefore, the correct answer is 336.

8) Use the unit price to find the total price. You buy 9 gallons of gas at $1.92 per gallon.

$8.64

12) A store sells packages of pencils. Which package offers the best unit price?

12 pencils for $3.36

15 pencils for $4.05

16 pencils for $4.16

13 pencils for $3.25

You must get the unit price for each package. To get the cost per pencil, divide the price by the number of pencils.

Explanation

13) A bookstore advertises 5 notebooks for $7.75. At this rate, how much will 7 notebooks cost?

$54.25

$8.00

$10.85

$1.55

The cost of 5 notebooks is $7.75, so the cost of 1 notebook is $7.75/5 = $1.55. Therefore, the cost of 7 notebooks will be 7 * $1.55 = $10.85.

Explanation

The cost of 5 notebooks is $7.75, so the cost of 1 notebook is $7.75/5 = $1.55. Therefore, the cost of 7 notebooks will be 7 * $1.55 = $10.85.
