  1. A basketball player made 24 out of 30 free throws. What percent of free throws did she make?

    Answer: 80%

    24 ÷ 30 = 0.8 = 80%.

  2. A solution of 40 liters is 15% alcohol. How many liters of pure alcohol are in the solution?

    Answer: 6 liters

    15% of 40 = 0.15 × 40 = 6 liters.

  3. If a car travels at 55 mph, how many feet does it travel in one second? (1 mile = 5,280 feet; 1 hour = 3,600 seconds)

    Answer: 80.7 ft/s

    55 × 5,280 ÷ 3,600 = 290,400 ÷ 3,600 ≈ 80.7 ft/s.

  4. A store is having a 30%-off sale. After the discount, a jacket costs $84. What was the original price?

    Answer: $120.00

    If 70% of the original price = $84, then original = $84 ÷ 0.70 = $120.

  5. A square photo with sides of 5 cm is enlarged so that its area doubles. What is the side length of the enlarged photo, to the nearest tenth of a cm?

    Answer: 7.1 cm

    Original area = 25 cm²; new area = 50 cm²; new side = √50 ≈ 7.07 ≈ 7.1 cm.

  6. A fruit punch recipe mixes orange juice and pineapple juice in a ratio of 3:2. How many liters of pineapple juice are needed to make 25 liters of punch?

    Answer: 10 liters

    Pineapple juice fraction = 2/(3+2) = 2/5; 2/5 × 25 = 10 liters.

  7. A 500-page book has a ratio of text pages to image pages of 4:1. How many pages contain images?

    Answer: 100 pages

    Image fraction = 1/(4+1) = 1/5; 1/5 × 500 = 100 pages.
