  1. If a recipe requires 2.5 cups of flour for 12 cookies, how many cups are needed for 36 cookies?

    Answer: 7.5 cups

    36 cookies is 3× the recipe, so 2.5 × 3 = 7.5 cups.

  2. What is the median of the following set: 4, 7, 2, 9, 5?

    Answer: 5

    Ordered: 2, 4, 5, 7, 9 — the middle value is 5.

  3. A tank holds 500 gallons. If it is 40% full, how many gallons are in the tank?

    Answer: 200 gallons

    40% of 500 = 0.40 × 500 = 200 gallons.

  4. What is the result of (−6) × (−4)?

    Answer: 24

    A negative times a negative equals a positive: (−6) × (−4) = +24.

  5. Simplify: 18/24

    Answer: 3/4

    GCF of 18 and 24 is 6; 18÷6 = 3 and 24÷6 = 4, so 18/24 = 3/4.

  6. A right triangle has legs of length 6 and 8. What is the length of the hypotenuse?

    Answer: 10

    Using the Pythagorean theorem: 6² + 8² = 36 + 64 = 100, so the hypotenuse = √100 = 10.
