Question 1

A recipe calls for 2/3 cup of sugar to make one batch of cookies. How many cups of sugar are needed to make 4 batches?

Accepted Answer

2 2/3 cups

Answer

Multiply 2/3 by 4: (2/3) × 4 = 8/3. Converting to a mixed number: 8 ÷ 3 = 2 remainder 2, so 8/3 = 2 2/3 cups.

Question 2

Which of the following is equivalent to 5/8 expressed as a percent?

Accepted Answer

62.5%

Answer

Divide 5 by 8 to get the decimal: 5 ÷ 8 = 0.625. Multiply by 100 to convert to a percent: 0.625 × 100 = 62.5%.

Question 3

A jacket originally priced at $80 is on sale for 35% off. What is the sale price?

Accepted Answer

$52.00

Answer

Find the discount: 35% of $80 = 0.35 × 80 = $28. Subtract from the original price: $80 − $28 = $52.

Question 4

What is the value of −6 + (−4) − (−10)?

Accepted Answer

0

Answer

Subtracting a negative is the same as adding a positive: −6 + (−4) − (−10) = −6 − 4 + 10 = −10 + 10 = 0.

Question 5

A car travels 180 miles in 3 hours. At the same speed, how far will it travel in 5 hours?

Accepted Answer

300 miles

Answer

Find the speed: 180 ÷ 3 = 60 miles per hour. Then multiply by 5 hours: 60 × 5 = 300 miles.
