Odpowiedź:
e) 8/9 - 1/3 = 8/9 - 3/9 = 5/9
f) 3/10 - 1/5 = 3/10 - 2/10 = 1/10
h) 5/7 - 1/4 = 20/28 - 7/28 = 13/28
m) 4 1/4 - 2 2/3 = 4 3/12 - 2 8/12 = 3 15/12 - 2 8/12 = 1 7/12
n) 5 1/9 - 1 5/6 = 5 2/18 - 1 15/18 = 4 20/18 - 1 15/18 = 3 5/18
o) 3 1/15 - 1 1/10 = 3 2/30 - 1 3/30 = 2 32/30 - 1 3/30 = 1 29/30
p) 5 5/13 - 3 1/2 = 5 10/26 - 3 13/26 = 4 36/26 - 3 13/26 = 1 23/36
