1. 14 4/5+ 4/15 = 14 12/15 + 4/15 = 14 16/15  = 15 1/15 (226/15)

2. 226/15:113/5 = 226/15*5/113 = 2/3

3. 2/3 : 10/3 = 2/3*3/10=1/5

4. 8/3:2 = 8/3*1/2 = 8/6

5. 8/6+1/5 = 40/30+6/30 = 46/30 = 1 8/15

1. 13/4+13/6 = 39/12+26/12 = 65/12

2. 65/12:13/5 = 65/12*5/13 = 25/12

3. 25/12:5/18 = 25/12*18/5 = 15/2

4. 31/6:31 = 31/6*1/31= 1/6
