Question: There are 88 books for every 16 bookshelves in a college library. What is the ratio of the number of shelves to that of books?
A ) 2 : 11
B ) 3 : 8
C ) 8 : 3
D ) 11 : 2
Steps to derive
1 shelvesbooks = 1688
2 = 16 ÷ 888 ÷ 8
[Divide both numerator and denominator by their GCF 8.]
3 = 211
4 So, the ratio of the number of shelves to books is 2 : 11.
Hence the right answer is Option A
