Answer
68
Work Step by Step
We first apply the distributive property. Then, we simplify the resultant expression:
$64(\frac{3}{16}+\frac{5}{8}-\frac{1}{4}+\frac{1}{2})$
=$64(\frac{3}{16})+64(\frac{5}{8})-64(\frac{1}{4})+64(\frac{1}{2})$
=$4(\frac{3}{1})+8(\frac{5}{1})-16(\frac{1}{1})+32(\frac{1}{1})$
=$4(3)+8(5)-16(1)+32(1)$
=$12+40-16+32$
=$52-16+32$
=$52+16$
=$68$
