The number of tim's stamps is 3/4 the number of david's stamps.if tim gives 1/2 of his stamps to david,what will be the ratio of the number of tim's stamps to the number of david's stamps?

Answer 1

Number of stamps for david -- 4 x
number of stamps for Tim = 3x

after give-away,
Tim has 1.5x
David has 5.5x

ratio of Tim : David
= 1.5x : 5.5x
= 1.5 : 5.5
= 15 : 55
= 3 : 11
