Answer 1

5/11 - 2/5 = 25/55 - 22/55 = 3/55

5/9 - 1/2 = 10/18 - 9/18 =1/18

2/3 - 1/4 = 8/12 - 3/12 = 5/12

3/5 - 2/7 = 21/35 - 10/35 = 11/35

7/12 - 1/8 = 14/24 - 3/24 = 11/24

11/15 - 3/10 = 22/30 - 9/30 = 13/30

7/9 - 4/15 = 35/45 - 12/45 = 23/45

5/6 - 2/15 = 25/30 - 4/30 = 21/30

 

 

mam nadzieję, że pomogłam, pozdrawiam, wroniaak :)

Answer 2

25/55-22/55=3/55

10/18-9/18=1/18

8/12-3/12=5/12

21/35-10/35=11/35

14/24-3/24=11/24

22/30-9/30=13/30

70/90-24/90=46/90

25/30-4/30=21/30
