Question

Fiona wants to estimate the product (8.7)(3.0). Which expression shows each factor rounded to the nearest whole number?
(9)(4)
(9)(3)
(8)(3)
(8)(4)

Answer 1

To estimate the product \( (8.7)(3.0) \) by rounding each factor to the nearest whole number:

- Round \( 8.7 \) to the nearest whole number: \( 8.7 \) rounds to \( 9 \).
- Round \( 3.0 \) to the nearest whole number: \( 3.0 \) rounds to \( 3 \).

So, the expression that shows each factor rounded to the nearest whole number is \( (9)(3) \).
