Lia wants to estimate 4 1/7 x 3 3/5 To estimate, she simplifies the expression 4 x 3 1/2.

Is Lia's estimate a close estimate, an underestimate, or an overestimate?

A. underestimate

B. overestimate

C. close estimate

Given:

4 1/7 * 3 3/5

4 1/7 = (4*7) + 1/7 = 29/7

3 3/5 = (3*5) + 3/5 = 18/5

29/7 * 18/5 = 29 * 18 / 7 * 5 = 522 / 35 = 14.91

Simplified expression.

4 x 3 1/2

3 1/2 = (3*2) + 1/2 = 7/2

4 * 7/2 = 4*7 / 2 = 28 / 2 = 14

It is a close estimate. Actual: 14.91 vs Estimate: 14
