Question

For Me To Pass Me Exam help!! Thankss : A public library has fiction and nonfiction books in the ratio three colon two. If the library has three hundred sixty fiction books, how many nonfiction books does it have?

Answer 1

if ratio is 3:2 then we can divide by the total: 5

and then multiply by 2 to get the number of nonfictions

360/5 = 72

72*2 = 144

Answer 2

another way to think about it is for some number x

fiction = 3x

non fiction = 2x

and total = 3x + 2x = 5x = 360

5x = 360

x = 72

nonfiction = 2x = 2*72 = 144
