To determine

To find :

The difference of the expression.

Answer to Problem 49E

Thedifference of the expression is $15.5$ .

Explanation of Solution

Given information:

Consider theexpression $-6\frac{7}{12}-8\frac{11}{12}$ .

Calculation :

Consider the following expression $-6\frac{7}{12}-8\frac{11}{12}$ .

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

Therefore,

  $\begin{array}{l}-6\frac{7}{12}-8\frac{11}{12}\left[\text{Change mixed fraction}\right]\\ =-\frac{79}{12}-\frac{107}{12}\left[\text{Applying LCM property}\right]\\ =\frac{-79+107}{12}\left[\text{Subtract}\right]\\ =\frac{186}{12}\left[\text{Divide}\right]\\ =15.5\end{array}$

The difference of the expression is $15.5$ .
