Answer
Estimate: 7
Exact: 8.45
Work Step by Step
We need to divide:
$0.8\overline{)6.76}$
First, we estimate by rounding:
$~~~7$
$1\overline{)7}$
Next, we find the exact answer. We move the decimal place once to the right to simplify the division:
$~~~~~8.45$
$8\overline{)67.60}$
$~~~\underline{64}$
$~~~~~~36$
$~~~~~~\underline{32}$
$~~~~~~~~40$
$~~~~~~~~\underline{40}$
$~~~~~~~~~~0$
We see that our estimate and exact answers are a bit off from each other.
