Chapter 4.3, Problem 79CCR

To determine

To find: thevalue of expression.

Answer to Problem 79CCR

The value of expression is $-\frac{1}{8}$ .

Explanation of Solution

Given information:

Theexpression is $-\frac{1}{2}+\frac{3}{8}$ .

Calculation : to find the value of expression, first take L.C.M and then simplify it,

  $\begin{array}{l}-\frac{1}{2}+\frac{3}{8}=\frac{-4+3}{8}\text{ [take L}\text{.C}\text{.M}\text{. of denominator]}\\ -\frac{1}{2}+\frac{3}{8}=-\frac{1}{8}\text{ [simply]}\end{array}$

Thus, the value of expression is $-\frac{1}{8}$ .
