Answer

30

Work Step by Step

We first apply the distributive property. Then, we simplify the resultant expression: $48(\frac{5}{12}-\frac{1}{6}+\frac{3}{8})$ =$48(\frac{5}{12})-48(\frac{1}{6})+48(\frac{3}{8})$ =$4(\frac{5}{1})-8(\frac{1}{1})+6(\frac{3}{1})$ =$4(5)-8(1)+6(3)$ =$20-8+18$ =$12+18$ =$30$
