2/3 * 5 1/2 * 2 * 7 5/6 * 9/11 = ______________?
Correct answer: C. 47
- A. 4 9/11
- B. 37
- C. 47
- D. 74
Explanation
Convert the mixed numbers: 5 1/2 = 11/2 and 7 5/6 = 47/6. Then 2/3 x 11/2 x 2 x 47/6 x 9/11 simplifies by cancellation to 47, so option c is correct. Option d, 74, usually comes from failing to cancel the factor 2 correctly.
