Answer
53.75 inches
Work Step by Step
Convert the measurements to like fractions to compare.
left $53\frac{1}{2}=53\frac{1\times4}{2\times4}=53\frac{4}{8}$
center $53\frac{3}{4}=53\frac{3\times2}{4\times2}=53\frac{6}{8}$
right $53\frac{3}{8}$
The center measurement is the longest because it has the largest numerator (6).
Convert the center length to a decimal for the gridded response.
$53\frac{6}{8}=53.75$
