  1. A store sells apples for $1.25 each. If Maria buys 8 apples and pays with a $20 bill, how much change will she receive?

    Answer: $10.00

    8 apples × $1.25 = $10.00. Change = $20.00 − $10.00 = $10.00.

  2. Which of the following is equivalent to 3/8 expressed as a decimal?

    Answer: 0.375

    3 ÷ 8 = 0.375. Dividing the numerator by the denominator converts a fraction to a decimal.

  3. What is 15% of 240?

    Answer: 36

    15% of 240 = 0.15 × 240 = 36.

  4. Order the following numbers from least to greatest: −3, 1/2, −1.5, 0, 2

    Answer: −3, −1.5, 0, 1/2, 2

    On a number line: −3 < −1.5 < 0 < 0.5 < 2. Converting all to decimals makes comparison straightforward.

  5. A recipe calls for 2 1/4 cups of flour. If you want to make 1.5 times the recipe, how many cups of flour do you need?

    Answer: 3 3/8 cups

    2 1/4 × 1.5 = 9/4 × 3/2 = 27/8 = 3 3/8 cups.

  6. The population of a town was 45,000 in 2010 and 54,000 in 2020. What was the percent increase in population?

    Answer: 20%

    Percent increase = (54,000 − 45,000) / 45,000 × 100 = 9,000 / 45,000 × 100 = 20%.
