A= 11/12 + 1/2
1/2’yi 6yla carparız = 6/12
A= 11/12 + 6/12 = 17/12
A= 17/12
B= 1/6 +1/2
1/2yi 3le carparız =3/6
B= 1/6 + 3/6 = 4/6
B= 4/6
C= 11/12 + 3/4
3/4ü 3le carparız = 9/12
C= 11/12 + 9/12 = 20/12
C= 20/12
D=1/6 + 3/4
1/6yı 4le carparız = 4/24
3/4ü 6yla carparız = 18/24
D= 4/24 + 18/24 = 24/24
a) A - D = 17/12 - 24/24
17/2yi 2yle carparız = 34/24
34/24 - 24/24 = 10/24
a) = 10/24
b) B + C = 4/6 + 20/12
4/6yı 2yle carparız = 8/12
8/12 + 20/12 = 28/12
b) = 28/12
