Odpowiedź:
1/9 + 4/9 = 5/9
2 i 2/3 + 5 i 1/2 = 2 i 4/6 + 5 i 3/6 = 7 i 7/6 = 8 i 1/6
2/12 + 4/9 = 6/36 + 16/36 = 22/36 = 11/18
2 i 7/8 + 4 i 5/6 + 1 i 5/12 = 2 i 21/24 + 4 i 20/24 + 1 i 10/24 = 7 i 51/24 = 9 i 3/24 = 9 i 1/8
3 i 4/15 - 2 i 6/15 = 2 i 19/15 - 2 i 6/15 = 13/15
3/5 - 8/25 = 15/25 - 8/25 = 7/25
Odpowiedź:
a) 1/9+4/9 = 5/9
b) 2 2/3+5 1/2 = 8/3+11/2 = 16/6 + 33/6 = 49/6 = 8 1/6
c) 2/12+4/9 = 6/36 + 16/36 = 22/36
d) 2 7/8+4 5/6+1 5/12 = 23/8+29/6+17/12 = 69/24 + 116/24 + 34/24 = 219/24 = 9 3/24
e) 3 4/15-2 6/15 = 49/15 - 36/15 = 13/15
f) 3/5-8/25 = 15/25 - 8/25 = 7/25
Pls daj naj :)
