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

    Answer: 84 cm²

    Area of a rectangle = length × width = 12 × 7 = 84 cm².

  2. Which of the following is equivalent to 3/4?

    Answer: 0.75

    3 ÷ 4 = 0.75, so 3/4 = 0.75.

  3. If x + 9 = 21, what is the value of x?

    Answer: 12

    Subtract 9 from both sides: x = 21 − 9 = 12.

  4. A store sells 6 apples for $1.50. How much do 10 apples cost?

    Answer: $2.50

    Unit price = $1.50 ÷ 6 = $0.25 each; 10 × $0.25 = $2.50.

  5. What is the value of 5²?

    Answer: 25

    5² means 5 × 5 = 25.

  6. Order these fractions from least to greatest: 1/2, 2/5, 3/4.

    Answer: 2/5, 1/2, 3/4

    Converting to decimals: 2/5=0.40, 1/2=0.50, 3/4=0.75, so 2/5 < 1/2 < 3/4.

  7. A number is multiplied by 4 and then 6 is added. The result is 30. What is the original number?

    Answer: 6

    4n + 6 = 30 → 4n = 24 → n = 6.
