Answer
$Estimate: 54$ tons
$Exact: \displaystyle 53\frac{5}{12}$ tons
Work Step by Step
We need to find the sum of the newspaper weights:
$\displaystyle 28\frac{2}{3}+24\frac{3}{4}$
First, we estimate by rounding:
$\displaystyle 28\frac{2}{3}+24\frac{3}{4}$
$\approx 29+25$
$\approx 54$ tons
Next, we get the exact answer:
$\displaystyle 28\frac{8}{12}+24\frac{9}{12}$
$=\displaystyle 52\frac{17}{12}$
$=\displaystyle 53\frac{5}{12}$ tons
The exact result is fairly close to the estimate.
