  1. A classroom has 24 students. If 3/8 of the students are in the reading group, how many students are NOT in the reading group?

    Answer: 15

    3/8 of 24 = 9 students in the reading group, so 24 − 9 = 15 are not.

  2. A number line shows points at −3, 0, and 4. What is the distance between the points at −3 and 4?

    Answer: 7

    Distance = 4 − (−3) = 4 + 3 = 7.

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

    Answer: 5 × 3 + 5 × 2

    By the distributive property, 5(3 + 2) = 5 × 3 + 5 × 2 = 15 + 10 = 25.

  4. A student scores 82, 76, 90, and 88 on four tests. What is the student's average (mean) score?

    Answer: 85

    (82 + 76 + 90 + 88) ÷ 4 = 336 ÷ 4 = 84.

  5. Which of the following is a prime number?

    Answer: 37

    37 has no factors other than 1 and itself; the others are divisible by 3 or 7.

  6. A rectangle has a length of 12 cm and a width of 7 cm. What is its perimeter?

    Answer: 38 cm

    Perimeter = 2(length + width) = 2(12 + 7) = 2(19) = 38 cm.

  7. If x − 9 = 15, what is the value of x?

    Answer: 24

    Add 9 to both sides: x = 15 + 9 = 24.
