To determine

To find : The sum of the expression.

Answer to Problem 47E

Thesum of the expression is $17.36$ .

Explanation of Solution

Given information:

Consider theexpression $9\frac{8}{11}+7\frac{6}{11}$ .

Calculation :

Consider the following expression $9\frac{8}{11}+7\frac{6}{11}$ .

First the mixed fraction is needed to be converted into improper fraction and then addition is to be done.

Therefore,

  $\begin{array}{l}9\frac{8}{11}+7\frac{6}{11}\left[\text{Change mixed fraction}\right]\\ =\frac{107}{11}+\frac{83}{11}\left[\text{Applying LCM property}\right]\\ =\frac{107+83}{11}\left[\text{Addition}\right]\\ =\frac{191}{11}\left[\text{Divide}\right]\\ =17.36\end{array}$

The sum of the expression is $17.36$ .
