#### Answer

$Estimate: 59$ pounds
$Exact: \displaystyle 59\frac{11}{16}$ pounds

#### Work Step by Step

We need to find the difference in the pumpkins weights by subtracting:
$\displaystyle 1535\frac{3}{8}-1475\frac{11}{16}$
First, we approximate by rounding:
$\displaystyle 1535\frac{3}{8}-1475\frac{11}{16}$
$\approx 1535-1476$
$\approx 59$ pounds
Next, we obtain the exact answer:
$\displaystyle 1535\frac{3}{8}-1475\frac{11}{16}$
$=\displaystyle 1535\frac{6}{16}-1475\frac{11}{16}$
$=\displaystyle 1534\frac{22}{16}-1475\frac{11}{16}$
$=\displaystyle 59\frac{11}{16}$ pounds
The exact result is fairly close to the estimate.
