1) Let's subtract that fraction and a mixed number
2) Let's convert it, keeping the denominator and Multiplying it by the whole number and add to the numerator:
[tex]\begin{gathered} \frac{5}{8}-1\frac{7}{8}= \\ \frac{5}{8}-\frac{8\cdot1+7}{8}= \\ \frac{5}{8}-\frac{15}{8}=\frac{-10}{8} \end{gathered}[/tex]3) Finally let's subtract, and in this case, we can simplify t
