Question

Round each mixed number to the nearest whole number. Then, estimate the product.8 9/10x1 4/5

Answer 1

9 × 2 = 18

Explanation:

8 9/10 is closer to 9 than it is to 8. So you round 8 9/10 up to 9.

1 4/5 is closer to 2 than to 1. So round it up to 2.

Use the rounded numbers to estimate the product. 9 × 2 is 18

The estimate is 18.
