Answer 1

1 5/6 + 2 4/7 =11/6+18/7=185/42=4 17/42
(3 2/3) do potęgi 2=(5/3)²=25/9=2 7/9
4 6/7 - 2 1/5 =34/7-11/5=93/35=2 23/35
8 2/9 - 3/58 =74/9-3/58=4265/522=8 89/522
7/15 * 3/4 =7/20
4/7 : 8/21 =3/2=1 1/2
2 2/3 * 1 3/4 =8/3*7/4=14/3=4 2/3
6/13 : 3 3/5 =6/13:18/5=5/39
1 4/5 + 2 5/6 = 9/5+17/6=139/30=4 19/30
5 3/4 - 2 1/7 =23/4-15/7=101/28=3 17/28
2 3/4 do potęgi 2 =5/4²=5/16
6 2/9 - 4 3/8 =56/9-35/8=133/72=1 61/72
5/13 * 7/12 =35/156
3/7 : 6/35 =5/2=2 1/2
3 2/3 * 4 1/2 =11/3*9/2=33/2=16 1/2
4/11 : 2 2/3 =4/11:8/3=3/22
