Answer 1

8 1/5 - [6 1/4 - (4 1/3 - 2 1/2) = 41/5 - [25/4 - (13/3-5/2)] = 41/5-(25/4-11/6) = 41/5-53/12 = 492/60 - 265/60 = 227/60 = 3 47/60

6 1/2 - [5 1/3 - (4 1/4 - 3 1/5 )] =6 1/2 - [5 1/3 - 1 1/20] = 6 1/2 - 4 17/60 = 2 13/60

8 5/36 - 3 7/9 - 2 1/8 - 1 7/18 = 8 10/72 - 3 56/72 - 2 9/72 - 1 28/72 = 61/72
