Chapter 8.7, Problem 50SR

To determine

To calculate: To find the sum in simplest form

Answer to Problem 50SR

Sum is $1\frac{3}{40}$

Explanation of Solution

Given information: Expression is $\frac{7}{8}+\frac{2}{10}$

Calculation:

Expression is given as

  $\frac{7}{8}+\frac{2}{10}$

On solving above expression,

  $\begin{array}{l}\frac{7}{8}+\frac{2}{10}=\frac{7\times 5}{8\times 5}+\frac{2\times 4}{10\times 4}\\ \frac{7}{8}+\frac{2}{10}=\frac{35}{40}+\frac{8}{40}\\ \frac{7}{8}+\frac{2}{10}=\frac{35+8}{40}\\ \frac{7}{8}+\frac{2}{10}=\frac{43}{40}\\ \frac{7}{8}+\frac{2}{10}=1\frac{3}{40}\end{array}$

Hence, sum is $1\frac{3}{40}$
