Question

Kolby read 108 books in one year.If he reads the same number of books each month,how many books will he read in 5 months?

Answer 1

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

Answer 2

1 year = 12 months


`(books)/(months) =books/per/month \\ \\ (108)/(12)= 9`

Kolby reads 9 books per month.


`9*5=45`

He will read 45 books in 5 months.
