Question

7. Estimate the product by rounding each number to the nearest ten.

72 × 596

Answer 1

42,000

Explanation:

72 rounds to 70 because two is not 5 or greater so it rounds down to zero. 596 rounds up to 600 because 6 is greater or equal to 5 so you round up. Since there is already a 9 in the tens place, you have to add 1 to the hundreds place in order to round up. So the equation would be 70x600= 42,000.

Answer 2

42 000

Explanation:

72 ≈ 70 (2 is from 1-4 so round down)

596 ≈ 600 (6 is from 5-9 so round up)

72 × 596 ≈ 70 × 600

= 42 000
