1/2 + 1/3 + 1/4 = 6/12 + 4/12+ 3/12 = 13/12 = 1 1/12
1 2/5 + 3 4/10 + 2 1/2=1 4/10 + 3 4/10 + 2 5/10 = 6 13/10 = 7 3/10
3 3/4 - 2 2/3 + 6 - 3 5/6 = 3 9/12 - 2 8/12 + 6 - 3 10/12 = 1 1/12 + 5 2/12 = 6 3/12 = 6 1/4
10- (2 1/9 - 1/2 + 1 5/6) = 10 - (2 2/18 - 9/18 + 1 15/18) = 10 - 2 6/18 = 7 12/18 = 7 1/3

10- (2 1/9 - 1/2) + 1 5/6 = 10 - (2 2/18 - 9/18) + 1 15/18 = 10 - 1 11/18 + 1 15/18 =
8 7/18 + 1 15/18 = 9 22/18 = 10 4/18
