Abel had 3 times as many books as Thomas. Abel donated 1/4 of his books to charity. What was the ratio of the number of books Thomas had to the number of books Abel had in the end?

 

(1)     3:4

(2)     4:9

(3)     9:4

(4)     9:7

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A : T = 3 : 1       or     3x : x

 

3x - (3x/4) = 2.25x

 

T : A = 1 : 2.25      or     4 / 9
