  1. If a car travels 180 miles in 3 hours, what is its average speed?

    Answer: 60 mph

    Average speed = distance ÷ time = 180 ÷ 3 = 60 mph.

  2. Which of the following numbers is irrational?

    Answer: √2

    √2 ≈ 1.41421… is non-terminating and non-repeating, so it cannot be expressed as a ratio of integers.

  3. Simplify using order of operations: (3 + 4) × 2 − 6 ÷ 3

    Answer: 12

    Parentheses first: (3+4)=7; then multiply: 7×2=14; then divide: 6÷3=2; finally subtract: 14−2=12.

  4. A recipe calls for 2½ cups of flour. To make 1.5 times the recipe, how many cups are needed?

    Answer: 3¾ cups

    2.5 × 1.5 = 3.75 cups, which equals 3¾ cups.

  5. What is 5/8 expressed as a decimal?

    Answer: 0.625

    Dividing 5 by 8 gives 0.625.

  6. If x : y = 3 : 5 and y = 25, what is the value of x?

    Answer: 15

    Set up the proportion x/25 = 3/5; cross-multiply to get 5x = 75, so x = 15.

  7. Which expression represents the number 'three hundred forty-two thousandths'?

    Answer: 0.342

    Thousandths means the denominator is 1,000, so three hundred forty-two thousandths = 342/1000 = 0.342.
