the ratio to the number of mystery books to the number of science fiction books is 4:3
the ratio of the number of science fiction books to the number of biographies is 4:5
if there are 48 science fiction books, find the total number of books using bar model
Answered by Steve
m/sf = 4/3
sf/b = 4/5

sf = 48, so

m/48 = 4/3
m = 64

48/b = 4/5
b = 60

sf+m+b = 48+64+60 = 172

maybe you can fit that into your bar model.
