Answer

$-1$

Work Step by Step

In adding two numbers with the same sign, perform the following steps: (1) Add their absolute values. $|-\frac{7}{8}| + |-\frac{1}{8}| = \frac{7}{8} + \frac{1}{8} = \frac{8}{8}=1$ (2) The sum must have sign common to the addends. $-\frac{7}{8}+(-\frac{1}{8}) = -1$ Thus, the sum is $-1$.
