1/6+ 1/4 = 2/12 + 3/12 = 5/12
1/9 + 2/18 = 2/18 + 2/18 = 4/18 = 2/9
odejmowanie
12/24 - 1/8 = 12/24 - 3/24= 9/24 = 3/8
15/16 - 1/2 = 15/16 - 8/16 = 7/16
mnożenie
8/12 * 3/4 = 2/4 * 1 = 2/4 = 1/2
3/9 * 6/12 = 1/3 * 2/4 = 2/12 = 1/6
dzielenie
8/12 : 3/4 = 8/12 * 4/3 = 8/3 * 1/3 = 8/9
3/9 : 6/12 = 3/9 * 12/6 = 1/3 * 4/2 = 4/6 = 2/3
Odpowiedź:
1/2 + 1/3 = 3/6 + 2/6 = 5/6
3/8 + 1/2 = 3/8 + 4/8 = 7/8
6/5 - 7/15 = 18/15 - 7/15 = 11/15
5/10 - 1/5 = 5/10 - 2/10 = 3/10
2/5 * 1/2 = 2/10 = 1/5
2/3 * 1/8 = 2/24 = 1/12
3/2 : 4/2 = 3/2 * 2/4 = 6/8 = 3/4
3/7 : 5/10 = 3/7 * 10/5 = 30/35 = 6/7
