If someone read a total of 16 books over 4 months, how many books would they have read over 5 months?

Question

Simon read a total of 16 books over 4 months. After belonging to the book club for 5 months, how many books will Simon have read in all?

Answer 1

books per month = 16/4 = 4 bpm

4(5) = 20 books in 5 months.

 

Or, set up a proportion

 

16 is to 4 as x is to 5

16/4 = x/5

4 = x/5

4(5) = x

20 = x
