Zad.1 a)
1 i 3/7 + 2 i 6/7 = 3 + 9/7 = 3 + 1 i 2/7 = 4 i 2/7
3/4+5/12= 9/12+5/12= 14/12= 1 i 2/12= 1 i 1/6
4 i 8/9+4 i 2/3 = 4 i 8/9 + 4 i 6/9 = 8 i 14/9 = 9 i 5/9
b) 6 i 1/6+ 3 i 3/8= 6 i 4/24 +3 i 9/24 = 9 i 13/24
1/2 + 2/3 + 3/4 = 6/12 + 8/12 + 9/12 = 23/12 = 1 i 11/12
4 + 5 i 2/5 + 2 i 1/4 = 4 + 5 i 8/20 + 2 i 5/20 = 11 i 13/20
Zad.2 a)
10 i 1/3 - 3 = 7 i 1/3
10 - 7 i 3/5= 2 i 2/5
2 i 3/8 - 1 i 5/8 = 19/8 - 13/8 = 6/8 = 3/4
b) 6/7 - 5/6 = 36/42 - 35/42 = 1/42
2 i 3/4 - 1 i 2/3 = 2 i 9/12 - 1 i 8/12 = 1 i 1/12
4 i 1/3 - 5/6 = 4 i 4/12 - 10/12 = 52/12 - 10/12 = 42/12 = 3 i 6/12 = 3 i 1/2
c) 8 i 3/4 - 2 i 1/8 = 8 i 6/8 - 2 i 1/8 = 6 i 5/8
4 i 4/5 - 1 i 1/7 = 4 i 28/35 - 1 i 5/35 = 3 i 23/35
8 i 1/2 - 6 i 5/7 = 8 i 7/14 - 6 i 10 14 = 119/14 - 94/14 = 25/14 = 1 i 11/14
Niestety z zadaniem 3 Ci nie pomoge bo nie umiem, ale pozostałe 2 masz zrobione.
