Chapter 1.5, Problem 34P

Find each difference.

$-\frac{7}{8}-\left(-\frac{1}{8}\right)$

To determine

To find: The difference of the expression $-\frac{7}{8}-\left(-\frac{1}{8}\right)$ .

Answer to Problem 34P

The difference of the expression $-\frac{7}{8}-\left(-\frac{1}{8}\right)$ is $-\frac{3}{4}$ .

Explanation of Solution

Given:

The expression is $-\frac{7}{8}-\left(-\frac{1}{8}\right)$ .

Calculation:

Solve $-\frac{7}{8}-\left(-\frac{1}{8}\right)$ as follows:

  $\begin{array}{c}-\frac{7}{8}-\left(-\frac{1}{8}\right)=-\frac{7}{8}+\frac{1}{8}\\ =\frac{-7+1}{8}\\ =\frac{-6}{8}\\ =-\frac{3}{4}\end{array}$

Thus, the difference of the expression $-\frac{7}{8}-\left(-\frac{1}{8}\right)$ is $-\frac{3}{4}$ .
