Simple....
so you have: \(\frac{7}{8}-(- \frac{3}{8} )\)
There's the law where if the number outside your parentheses is negative along with the number in the parentheses; it converts into positive...
-->>x-(-x)
--->>x+(+x)
This being said.....
\(\frac{7}{8} - (-\frac{3}{8} )\)
-->> \(\frac{7}{8} +(+ \frac{3}{8} )\)
-->>>\(\frac{10}{8}\)
But remember, you want to simplify it....
\(\frac{10}{8} = \frac{5}{4}\) (Decimal form..1.25)
Thus, your answer.
