Compare: 7/12 ___ 11/18
Answer: 7/12 < 11/18
Common denominator 36: 7/12 = 21/36, 11/18 = 22/36. Since 21 < 22, 7/12 < 11/18.
Which is greater: 15% of 200 or 20% of 140?
Answer: 15% of 200
15% of 200 = 30. 20% of 140 = 28. 30 > 28.
Compare: (-3)² ___ -(3²)
Answer: (-3)² is larger
(-3)² = (-3) × (-3) = 9. -(3²) = -(9) = -9. Since 9 > -9, (-3)² is larger.
Which is larger: the perimeter of a square with side 8 or the circumference of a circle with radius 5 (use π ≈ 3.14)?
Answer: Square's perimeter
Square perimeter = 4 × 8 = 32. Circle circumference = 2 × 3.14 × 5 = 31.4. 32 > 31.4.
Compare: 2/3 + 1/4 ___ 3/4 + 1/6
Answer: They are equal
Left: 2/3 + 1/4 = 8/12 + 3/12 = 11/12. Right: 3/4 + 1/6 = 9/12 + 2/12 = 11/12. They are equal.
Which is greater: 4! (4 factorial) or 3³?
Answer: 3³ is greater
4! = 4 x 3 x 2 x 1 = 24. 3^3 = 3 x 3 x 3 = 27. Since 27 > 24, 3 cubed is greater.
