Answer 1

 

3/7+2/5 = 15/35+14/35=29/35

3/11 + 1/2 = 6/22+11/22=17/22

4/5 + 3/4 =16/20+15/20=31/20= 1 11/20

8/9 - 3/4 = 32/36- 27/36 = 5/36

11/12 - 2/5 = 55/60- 24/60=31/60

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

1/3+1/6= 2/6+1/ 6=3/6

2/7 + 4/21 =  6/21+4/21= 10/21

2/5+1/20= 8/5+1/20=9/20

11/15-1/3=11/15 - 5/15 = 6/15

25/27 - 4/9 = 25/27 - 12/27= 13/27

23/24- 5/12= 23/24-10/24=13/24

4/15+7/10=8/30+21/30=29/30

9/12+5/16= 36/48+ 15/48= 51/48=1 3/48= 1 1/16

 

 3/4-3/10 = 15/20- 6/20= 9/20

21/24-5/36= 63/72- 10/72= 53/72

4/9+7/8=32/72+63/72= 95/72=1 23/72

4/9+2/5= 20/45+ 16/45= 36/45=12/15

7/8+6/7=  49/56+48/56=97/56= 1 41/56

2/5+6/7= 14/35+ 30/35= 44/35=1 9/35

 

 

 

 uff wreszcie skonczone     licze na naj!!
