  1. A recipe calls for 2 1/3 cups of flour. If you want to make 1.5 times the recipe, how much flour do you need?

    Answer: 3 1/2 cups

    2 1/3 = 7/3. Multiply: 7/3 × 3/2 = 21/6 = 7/2 = 3 1/2 cups.

  2. Simplify: √(36/49)

    Answer: 6/7

    √(36/49) = √36/√49 = 6/7.

  3. What is 4/5 − 1/3?

    Answer: 7/15

    LCD of 5 and 3 is 15. 4/5 = 12/15; 1/3 = 5/15. Difference: 12/15 − 5/15 = 7/15.

  4. Estimate √75 to the nearest integer.

    Answer: 9

    8² = 64 and 9² = 81. Since 75 is between these, √75 is between 8 and 9. Since 75 is closer to 81 than to 64 (75−64=11 vs 81−75=6), √75 ≈ 8.66, which rounds to 9.

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

    Answer: 1

    LCD = 6. 1/2 = 3/6; 1/3 = 2/6; 1/6 = 1/6. Sum: 3/6 + 2/6 + 1/6 = 6/6 = 1.

  6. Which of the following fractions is equivalent to 0.375?

    Answer: 3/8

    3/8 = 0.375 because 3 ÷ 8 = 0.375. Alternatively, 0.375 = 375/1000 = 3/8 after simplification.
