Answer
Estimate: $630$
Exact: $568.11$
Work Step by Step
We need to multiply:
$~~~65.3$
$\times ~~\underline{8.7}$
First, we estimate by rounding:
$~~~~70$
$\times ~~\underline{9}$
$~~630$
Next, we find the exact answer:
$~~~~~~~~~65.3$
$~~~~\times ~~\underline{8.7}$
$~~~~~~~~4571$
$+~~~\underline{52240}$
$~~~~~568.11$
We see that our estimate and exact answers are a bit off from each other.
