Simple....
so you have: [tex] \frac{7}{8}-(- \frac{3}{8} )[/tex]
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.....
[tex] \frac{7}{8} - (-\frac{3}{8} )[/tex]
-->> [tex] \frac{7}{8} +(+ \frac{3}{8} )[/tex]
-->>>[tex] \frac{10}{8} [/tex]
But remember, you want to simplify it....
[tex] \frac{10}{8} = \frac{5}{4} [/tex] (Decimal form..1.25)
Thus, your answer.
