Odpowiedź:
1.
a = 1 4/5
b = 4 1/4
c = 5 12/7
d = 2 3/3
2.
a = 1 2/9
b = 11/7 = 1 4/7
c = 2 6/5 = 3 1/5
3.
a = 8/12 + 3/12 = 11/12
b = 25/45 + 27/45 = 52/45 = 1 7/45
c = 10/15 + 12/15 = 22/15 = 1 7/15
d = 30/56 + 24/56 = 54/56
e = 1 4/8 + 2 3/8 = 3 7/8
f = 6/27 = 1 7/27 = 1 13/27
g = 1 15/18 + 3 2/18 = 4 17/18
h = 2 3/30 + 1 14/30 = 3 17/30
