  1. A pizza is cut into 8 equal slices. If Maria eats 3 slices and Tom eats 2 slices, what fraction of the pizza remains?

    Answer: 3/8

    5 slices are eaten, leaving 3 out of 8, or 3/8.

  2. The temperature dropped from 45°F to 18°F overnight. By how many degrees did it drop?

    Answer: 27°F

    45 − 18 = 27°F.

  3. What is the area of a triangle with a base of 10 inches and a height of 6 inches?

    Answer: 30 sq in

    Area = ½ × base × height = ½ × 10 × 6 = 30 sq in.

  4. Simplify: 4² + √9

    Answer: 19

    4² = 16 and √9 = 3, so 16 + 3 = 19.

  5. A bag contains 4 red, 3 blue, and 5 green marbles. What is the probability of randomly picking a blue marble?

    Answer: 3/12

    There are 3 blue out of 12 total marbles, so probability = 3/12 = 1/4.

  6. Which expression is equivalent to 2(x + 5) − 3?

    Answer: 2x + 7

    2(x + 5) − 3 = 2x + 10 − 3 = 2x + 7.

  7. A recipe uses 2½ cups of flour for 24 cookies. How many cups are needed for 48 cookies?

    Answer: 5 cups

    Doubling the recipe means 2 × 2½ = 5 cups of flour.
