Answer 1

Odpowiedź:A) 1 3/4 + 1 5/6 = 7/4 + 11/6 = 21/12 + 22/12 = 43/12= 3 7/12

1 1/5 + 1 5/6 = 6/5 + 11/6 = 36/30 + 55/30 = 91/30 = 3 1/30

2 7/8 + 1 5/6 = 23/8 + 11/6 = 69/24 + 44/24 = 113/24 = 4 17/24

3 4/9 + 1 5/6 = 31/9 + 11/6 = 62/18 + 33/18 = 95/18 = 5 5/18

B) 1 9/19 - 3/5 = 28/19 - 3/5 = 114/95 - 57/95 = 57/95

2 1/15 - 3/5 = 31/15 - 3/5 = 31/15 - 9/15 = 22/15

1 1/3 - 3/5 = 4/3 - 3/5 = 20/15 - 9/15 = 11/15

3/4 - 3/5 = 15/20 - 12/20 = 3/20

4 1/2 - 3/5 = 9/2 - 3/5 = 45/10 - 6/10 = 39/10 = 3 9/10

5 7/20 - 3/5 = 107/20 - 3/5 = 107/20 - 12/20 = 95/20 = 4 15/20 = 4 3/4

1 3/7 - 3/5 = 10/7 - 3/5 = 50/35 - 21/35 = 29/35
