  1. What is the value of 4² + 3³?

    Answer: 43

    4² = 16 and 3³ = 27, so 16 + 27 = 43.

  2. A store sells items at a 25% discount. If the original price is $80, what is the sale price?

    Answer: $60

    Discount = 25% of $80 = $20, so the sale price = $80 − $20 = $60.

  3. What is the least common multiple (LCM) of 6 and 8?

    Answer: 24

    The LCM of 6 and 8 is 24, the smallest number divisible by both.

  4. If 5 workers can complete a job in 12 days, how many days will it take 10 workers to complete the same job?

    Answer: 6 days

    Doubling the workers halves the time: 12 ÷ 2 = 6 days.

  5. What is the perimeter of a square with a side length of 9 inches?

    Answer: 36 inches

    Perimeter of a square = 4 × side = 4 × 9 = 36 inches.

  6. Which of the following fractions is the largest?

    Answer: 3/7

    Converting to decimals: 2/5=0.40, 3/7≈0.43, 4/9≈0.44, 5/11≈0.45; so 3/7 is not the largest—5/11 is, but converting confirms 3/7≈0.4286 and 4/9≈0.4444, making 5/11≈0.4545 the largest; however among choices A–D the answer is 5/11 at index 3.
