Question

Mary is making 5 necklaces for her friends, and she needs 11/12 of a foot of string for each necklace. How many feet of string does she need?

A. 5 11/12

B. 4 7/12

C. 7 4/12

D. 3 7/12

Answer 1

5 x 11/12 = 55/12 = 4 7/12

B is correct

5 x less than 1 is less than 5, so you can eliminate A and C

11/12 is close to 1, so 5 x 11/12 is less than but close to 5. so eliminate D. That leaves B
