2/3 of 1/4 were torn.
1/3 of 1/4 were not torn.
1/3 * 1/4 = 1 * 1 / 3 * 4 = 1/12

Assuming that the fraction given him by his sister was torn at the same rate.
(1/4)(1/3)=1/12 given by his sister & not torn.

1/4(2/3) = 1/6 were torn
1/4-1/6 = 1/12 were not torn

what is to be found? it is: what fraction of his collection is his sis's and not torn?
let his collection be x stamps
so, x/4 was given by his sis
of which 2/3rd were torn...or 1/3rd were not torn
that is x/4 * 1/3 were from his sis and not torn
or, x/12
so 1/12 th of his collection is from his sis's and not torn!
hope it is not tooooo late!

1/4 of 2/3 so you have to get a common denomenator which is 12 so 3/12 of 8/12 which is (3/12) / (8/12) so for fractions you multiply by the recipricol which is (3/12) x (12/8) = 36/96 and can be reduced to 6/16 and can be further reduced to 3/8 and your answer is 3/8.

2/3rd of what were torn?
His entire collection or the part given by his sister.
