14 7/10 -(6 3/5 -2 5/6) = 10 14/15
1) 6 3/5- 2 5/6= 33/5-17/6= 198/30-85/30= 113/30
2) 14 7/10 - 113/30= 147/10-113/30= 441/30-113/30=328/30= 10 28/30= 10 14/15
10 14/15
14 7/10 -(6 3/5 -2 5/6) = 14 7/10 - 3 23/30 = 10 14/15
1. 6 3/5 - 2 5/6 = 33/5 - 17/6 = (33*6 - 17*5)/30 = (198-85)/30 = 113/30 = 3 23/30
2. 14 7/10 - 3 23/30 = 147/10 - 113/30 = (147*3-113)/30 =
(441-113)/30 = 328/30 = 10 28/30 = 10 14/15
