  1. What is 2/3 × 3/4?

    Answer: 1/2

    Multiply numerators and denominators: (2 × 3)/(3 × 4) = 6/12 = 1/2.

  2. Which of the following shows 0.045 written in expanded form?

    Answer: 4 × 0.01 + 5 × 0.001

    0.045 has 0 tenths, 4 hundredths, and 5 thousandths: 4 × 0.01 + 5 × 0.001.

  3. What is 3/5 ÷ 2?

    Answer: 3/10

    Dividing a fraction by a whole number: 3/5 ÷ 2 = 3/5 × 1/2 = 3/10.

  4. Order these from least to greatest: 0.6, 3/5, 0.59, 11/20

    Answer: 0.59, 11/20, 3/5, 0.6

    Convert all to decimals: 0.6 = 0.600, 3/5 = 0.600, 0.59 = 0.590, 11/20 = 0.550. Order: 0.59 (0.590) = 0.59, 11/20 (0.550) — wait, 11/20 = 0.55. So: 0.55 < 0.59 < 0.60 = 0.60.

  5. A tank holds 12.5 gallons of water. Each day, 0.25 gallons evaporate. How many days until the tank is empty?

    Answer: 50 days

    12.5 ÷ 0.25 = 50 days. Multiply both by 4: 50 ÷ 1 = 50.

  6. What is 4 1/3 + 2 3/4?

    Answer: 7 1/12

    Add whole numbers (4+2=6) and fractions separately. LCD of 3 and 4 is 12: 4/12 + 9/12 = 13/12 = 1 1/12. Total: 6 + 1 1/12 = 7 1/12.
