  1. A jacket originally costs $80 and is on sale for 25% off. What is the sale price?

    Answer: $60

    25% of $80 = $20 discount; $80 − $20 = $60.

  2. Which of the following correctly compares the numbers: −5 ___ −3?

    Answer: <

    On the number line, −5 is further left than −3, so −5 < −3.

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

    Answer: 24

    The product of two negative numbers is positive: (−6) × (−4) = 24.

  4. Which fraction is in simplest form?

    Answer: 5/11

    5 and 11 share no common factors other than 1, so 5/11 is already in simplest form.

  5. What is 0.045 written as a percent?

    Answer: 4.5%

    Multiply a decimal by 100 to convert to percent: 0.045 × 100 = 4.5%.

  6. Which of the following numbers is composite?

    Answer: 21

    21 = 3 × 7, so it has factors other than 1 and itself, making it composite.

  7. A car travels 150 miles in 2.5 hours. What is its average speed in miles per hour?

    Answer: 60 mph

    Speed = distance ÷ time = 150 ÷ 2.5 = 60 mph.
