The answer is 1/4.
1/2 equals 2/4,( which is the white t- shirt) so if you add 1/4 and 2/4 together, you'll get 3/4. 1 equals 4/4 if you change it into fraction.
4/4 - 3/4 is 1/4, which is the purple t- shirt. :)
1/2+1/4= 3/4 because 1/2=2/4 so 2/4+1/4 is 3/4 there is a total of 4/4 so 4/4-3/4 is 1/4. Hope it helped!
