Answer
The exact answer is 506 (not 56).
Work Step by Step
We need to check whether the answer given is reasonable:
$2428.8\div 4.8=56$
First, we estimate the answer by rounding:
$2428.8\div 4.8\approx 2000\div 5=400$
Since 56 and 400 are not very close, the given answer is not reasonable. We find the exact answer by dividing:
$4.8\overline{)2428.8}$
First, we move the decimal point one place to the right to simplify the division:
$~~~~~~~~~506$
$48\overline{)24288}$
$~~~~~~\underline{240}$
$~~~~~~~~~~28$
$~~~~~~~~~~~~\underline{0}$
$~~~~~~~~~~288$
$~~~~~~~~~~\underline{288}$
$~~~~~~~~~~~~~~0$
We see that the exact answer is 506 (not 56).
