1 year = 12 months

\(\frac{books}{months} =books/per/month \\ \\ \frac{108}{12}= 9\)

Kolby reads 9 books per month.

\(9*5=45\)

He will read 45 books in 5 months.

\(\frac{108}{12}= \frac{x}{5} \\ \\ \frac{a}{b} = \frac{c}{d} \to ad=bc \\ \\ 12x = 108 (5) \\ \\ 12x = 540 \\ \\ \boxed {x = 45} \\ \\\sf 45~ book~ can~be~read~in~5~months\)
