Answer

68

Work Step by Step

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