Chapter 4.1, Problem 63SR

To determine

To evaluate: $-\frac{5}{8}+\frac{3}{4}$

Answer to Problem 63SR

  $\frac{3}{8}$

Explanation of Solution

Given information:

  $-\frac{5}{8}+\frac{3}{4}$

Calculation:

  $-\frac{5}{8}$ can also be written as $-1+\frac{5}{8}$

The expression will become-

  $\begin{array}{l}-1+\frac{5}{8}+\frac{3}{4}=\frac{-32+20+24}{32}\\ \Rightarrow -1+\frac{5}{8}+\frac{3}{4}=\frac{12}{32}\\ \Rightarrow -1+\frac{5}{8}+\frac{3}{4}=\frac{3}{8}\end{array}$
