a = 13 1/3 : 12
a = 40/3 * 1/12
a = 10/9
a= 1 1/9
b : 4 1/2 = 2 2/3
b = 2 2/3 * 4 1/2
b = 8/3 * 9/2
b = 12/1
b = 12
2 5/6 : c = 4 1/4
c = 2 5/6 : 4 1/4
c = 17/6 : 17/4
c = 17/6 * 4/17
c = 2/3
2 2/5 * d = 9
d = 9 : 2 2/5
d = 9/1 : 12/5
d = 9/1 * 5/12
d = 45/12
d = 3 3/4
Na 100% dobrze :D Liczę na Naj ^^
