⅖-⅕=⅕
8/9 - 1/9 = 7/9
3.3/7 - 1/7=2.3/7
2.4/5 - 1.2/5 = 1.2/5
¾-¾=0
17/33 - 0 = 17/33

3.1/5=2. /5
2.2/8 - 7/8 = -4.8/7

1.
2/5-1/5=1\5
8/9-1/9=7/9
2⁴/₇-1/7=2³/₇
2⁴/₇-1²/₅=1²/₅
3/4-3/4=0
17/33-0=17/33
2.
3.1/5=2. /5 (napisz jeszcze raz ten przykład)
2.2/8-7/8=18/8 - 7/8 = 11/8 = 1³/₈
6.1/7-5/7= 43/7 - 5/7 = 38/7 = 5³/₇
10.9/20-13/20= 209/20 - 13/20 = 196/20 = 9⁴/₅
5.5/9-1.7/9= 50/9 - 16/9 = 34/9 = 3⁷/₉
7.1/6-2.5/6= 1/6 - 17/6 = -16/6 = -2²/₃
5.9/23-20/23= -11/23
25.5/10-10.9/10= 255/10 - 109/10 = 146/10 = 14³/₅
