Answer:
Here is your answer
Step-by-step explanation:
Given 5/8 books read then 168 are left.
So fraction left =
\begin{gathered}1 - \frac{5}{8} \\ = \frac{8}{8} - \frac{5}{8} = \frac{3}{8}\end{gathered}

so 3/8 is left
so this means 3/8 = 168
\begin{gathered}\frac{3}{8} = 168 \\ 1 = 168 \div \frac{3}{8} \\ 1 = 168 \times \frac{8}{3} = 448\end{gathered}
