5/8 + 5/6 = 15/24 + 20/24 = 35/24 = 1 11/24;

3/20 - 1/50 = 15/100 - 2/100 = 13/100;

8/51 + 3/17 = 8/51 + 9/51 = 17/51 = 1/3;

1/3 - 1/6 = 2/6 - 1/6 = 1/6;

0,35 - 1/20 = 35/100 - 1/20 = 7/20 - 1/20 = 6/20 = 3/10;

1/15 - 1/30 = 2/30 - 1/30 = 1/30;

3/10 - 2/15 = 9/30 - 4/30 = 5/30 = 1/6;

1/6 + 8/9 = 3/18 + 16/18 = 19/18 = 1 1/18;

3/5 + 0,4 = 0,6 + 0,4 = 1;

23/45 + 13/30 = 46/90 + 39/90 = 85/90 = 17/18;

1/4 + 0,5 = 1/4 + 5/10 = 1/4 + 1/2 = 1/4 + 2/4 = 3/4;

3/4 + 1/6 = 9/12 + 2/12 = 11/12;

13/14 - 5/42 = 39/42 - 5/42 = 34/42 = 17/21;

1/8 - 1/16 = 2/16 - 1/16 = 1/16;

7/12 + 11/18 = 21/36 + 22/36 = 43/36 = 1 7/36.
