Answer
The exact answer is 4.725 (not 47.25).
Work Step by Step
We need to check whether the answer given is reasonable:
$37.8\div 8=47.25$
First, we estimate the answer by rounding:
$37.8\div 8\approx 40\div 8=5$
Since 5 and 47.25 are not very close, the given answer is not reasonable. We find the exact answer by dividing:
$~~~~~~4.725$
$8\overline{)37.800}$
$~~~~\underline{32}$
$~~~~~~58$
$~~~~~~\underline{56}$
$~~~~~~~~~20$
$~~~~~~~~~\underline{16}$
$~~~~~~~~~~~40$
$~~~~~~~~~~~\underline{40}$
$~~~~~~~~~~~~~0$
We see that the exact answer is 4.725 (not 47.25).
