$-\frac{1}{8}y+24$

To factor -1/8 out you need to find a number that multiply by -1/8 be equal to each term in the expression.

To find those numbers you divide each term into -1/8:

$\begin{gathered} \frac{-\frac{1}{8}y}{-\frac{1}{8}}=y \\ \\ \frac{24}{-\frac{1}{8}}=-24\cdot8=-192 \end{gathered}$

Then, the factors are:

$-\frac{1}{8}y+24=-\frac{1}{8}(y-192)$
