Answer
The exact answer is 60.2 (not 6.2).
Work Step by Step
We need to check whether the answer given is reasonable:
$307.02\div 5.1=6.2$
First, we estimate the answer by rounding:
$307.02\div 5.1\approx 300\div 5=60$
Since 6.2 and 60 are not very close, the given answer is not reasonable. We find the exact answer by dividing:
$5.1\overline{)307.02}$
First, we move the decimal point one place to the right to simplify the division:
$~~~~~~~~~~60.2$
$51\overline{)3070.2}$
$~~~~~~\underline{306}$
$~~~~~~~~~~10$
$~~~~~~~~~~~~\underline{0}$
$~~~~~~~~~~102$
$~~~~~~~~~~\underline{102}$
$~~~~~~~~~~~~~~0$
We see that the exact answer is 60.2 (not 6.2).
