Odpowiedź:
a) 3 1/7 + 5 4/7 - 16/7= 8 5/7 - 16/7 = 8 5/7 - 2 2/7 = 6 3/7
b) 4 - (5 1/3 - 2 2/3) = 4 - ( 4 4/3 - 2 2/3) = 4 - 2 2/3 = 1 1/3
c) 5 5/8 - 7/8 = 4 13/8 - 7/8 = 4 6/8 = 4 3/4
d) 7 3/5 - 4/5 = 6 8/5 - 4/5 = 6 4/5
e) 5 1/4 - 2 3/4 = 4 5/4 - 2 3/4 = 2 2/4 = 2 1/2
f) 7 1/5 - 3 3/5 = 6 6/5 - 3 3/5 = 3 3/5
g) 9 1/8 - 2 7/8= 8 9/8 - 2 7/8 = 6 2/8 = 6 1/4
