1cała 1/8+2całe5/6=
2całe1/12-1cała2/3=

Answer 1

2/3 + 5/9 = 6/9 + 5/9= 11/9=1cała2/9
4/5 - 1/2 =8/10 -5/10=3/10
1cała1/8 + 2 całe 5/6=9/8 + 17/6=27/24 +  68/24= 95/24 =3 całe23/24
2całe1/12 - 1 cała2/3 =25/12 - 5/3 =25/12 - 20/12= 5/12

Answer 2

2/3 + 5/9 = 6/9 + 5/9 = 11/9 = 1cala 2/9
4/5 - 1/2 = 8/10 - 5/10 = 3/10
1cala 1/8 + 2cale 5/6 = 9/8 + 17/6 = 54/48 + 136/48 = 180/48 = 3cale 36/48 = 3cale 3/4
2cale 1/12 - 1cala 2/3 = 25/12 - 5/3 = 25/12 - 20/12 = 5/12
