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.
