  1. Compare: 3/4 ___ 5/7

    Answer: 3/4 > 5/7

    Convert to common denominator 28: 3/4 = 21/28 and 5/7 = 20/28. Since 21 > 20, 3/4 > 5/7.

  2. Which is greater: √50 or 7?

    Answer: √50 is greater

    √50 ≈ 7.07, which is greater than 7. Alternatively, 7² = 49 7.

  3. Compare: 0.625 ___ 5/8

    Answer: 0.625 = 5/8

    5/8 = 5 ÷ 8 = 0.625. They are equal.

  4. Which is larger: 2³ × 3 or 2 × 3²?

    Answer: 2³ × 3 is larger

    2³ × 3 = 8 × 3 = 24. 2 × 3² = 2 × 9 = 18. 24 > 18.

  5. Compare: 33⅓% of 90 ___ 25% of 120

    Answer: They are equal

    33⅓% of 90 = 1/3 × 90 = 30. 25% of 120 = 1/4 × 120 = 30. They are equal.

  6. Which is greater: the sum of the first 5 positive integers or the product of the first 3 positive integers multiplied by 2?

    Answer: The sum is greater

    Sum of first 5: 1+2+3+4+5 = 15. Product of first 3 x 2: (1x2x3) x 2 = 12. Since 15 > 12, the sum is greater.
