Chapter 11, Problem 5PSQ

To determine

Todetermine the sum or the difference.

Explanation of Solution

Given information:the expression is given as,

  $-\frac{4}{5}-\frac{2}{5}$

Calculation:the expression can be calculated TO-DETERMINE the sum or the difference,

  $\begin{array}{l}-\frac{4}{5}-\frac{2}{5}=\frac{-4-2}{5}\left[\text{ write sum of numerators over denominator}\right]\\ -\frac{4}{5}-\frac{2}{5}=\frac{-6}{5}\left[\text{add}\right]\\ -\frac{4}{5}-\frac{2}{5}=-\frac{6}{5}\end{array}$
