Chapter 8.7, Problem 48SR

To determine

To calculate: To find the sum in simplest form

Answer to Problem 48SR

Sum is $1\frac{1}{5}$

Explanation of Solution

Given information: Expression is $\frac{1}{2}+\frac{7}{10}$

Calculation:

Expression is given as

  $\frac{1}{2}+\frac{7}{10}$

On solving above expression,

  $\begin{array}{l}\frac{1}{2}+\frac{7}{10}=\frac{1\times 5}{2\times 5}+\frac{7\times 1}{10\times 1}\\ \frac{1}{2}+\frac{7}{10}=\frac{5}{10}+\frac{7}{10}\\ \frac{1}{2}+\frac{7}{10}=\frac{5+7}{10}\\ \frac{1}{2}+\frac{7}{10}=\frac{12}{10}\\ \frac{1}{2}+\frac{7}{10}=\frac{6}{5}\\ \frac{1}{2}+\frac{7}{10}=1\frac{1}{5}\end{array}$

Hence, sum is $1\frac{1}{5}$
