3 1/4 - 1 1/2 + 2 7/8 = 3 2/8 - 1 4/8 + 2 7/8 = 3 2/8 + 1 3/8 = 4 5/8
21 x 1 1/14 = 21 * 15/14 = 3 * 15/2 = 45/2 = 22 1/2
1 2/5 x 3 1/3 =7/5 * 10/3 = 7 * 2/3 = 14/3 = 4 2/3
nie mam tego
6 : 2 1/4 = 6 : 9/4 = 6 * 4/9 = 2 * 4/3 = 8/3 = 2 2/3
3 3/10 : 11 = 33/10 * 1/11 = 3/10
3 1/3 : 4 1/3 = 10/3 : 13/3 = 10/3 * 3/13 = 10 * 1/13 = 10/13
