2 i 3/5 - 1 i 7/10 = 2 i 6/10 - 1 i 7/10 = 1 i 16/10 - 1 i 7/10 = 9/10
7 i 3/8 - 3 i 5/6 = 7 i 9/24 - 3 i 20/24 = 6 i 33/24 - 3 i 20/24 = 3 i 13/24
3 i 3/8 * 8/9 = 27/8 * 8/9 = 3 Skracamy 27 i 9 przez 9 a 8 i 8 przez 8
4 i 1/5 : 7/10 = 21/5 * 10/7 = 6 skracamy 21 i 7 przez 7 a 10 i 5 przez 5
1,245 + 3/4 = 1,245 + 0,75 = 1,995
4,35 - 3/200 = 4,35 - 0,015 = 4,335
