Question

Ella wants to estimate the product (3.6)(7.8). Which expression shows each factor rounded to the nearest whole number?
(3)(7)
(4)(8)
(3)(8)
(4)(7)

Answer 1

To estimate the product \( (3.6)(7.8) \) by rounding each factor to the nearest whole number:

- Round \( 3.6 \) to the nearest whole number, which is \( 4 \).
- Round \( 7.8 \) to the nearest whole number, which is \( 8 \).

So, the expression that shows each factor rounded to the nearest whole number is:

\( (4)(8) \)
