Answer 2

a) 1 3/7 + 2 6/7 = 3 9/7=4 2/7

b) 3/4 + 5/12 = 9/12 + 5/12 = 14/12 = 1 2/12 = 1 1/6

c) 4 8/9 + 4 2/3 = 4 8/9 + 4 6/9 = 8 14/9 = 9 5/9

d) 6 1/6 + 3 3/8 = 6 4/24 + 3 9/24 = 15 13/24

e) 1/2 + 2/3 + 3/4 = 6/12 + 8/12 + 9/12 = 23/12 = 1 11/12

f) 4 + 5 2/5 + 2 1/2 = 4 + 5 4/10 + 2 5/10 = 11 9/10

Zadanie 2.

a) 10 1/3 - 3 = 7 1/3

b) 10 - 7 3/5 = 9 5/5 - 7 3/5 = 2 2/5

c) 4 8/9 - 4 2/3 = 4 8/9 - 4 6/9 = 2/9

d) 6/7 - 5/6 = 36/42 - 35/42 = 1/42

e) 2 3/4 - 1 2/3 = 2 9/12 - 1 8/12 = 1 1/12

f) 4 1/3 - 5/6 = 4 2/6 - 5/6 = 3 8/6 - 5/6 = 3 3/6 = 3 1/2
