a) 3 1/3 : 5/6 - 3/4 = 10/3 x 6/5 - 3/4 = 16/4 - 3/4 = 13/4 = 3 1/4
b) 2 2/3 - 2/3 x 2 1/4 = 8/3 - 2/3 x 9/4 = 8/3 - 2/3 x 9/4 = 8/3 - 1/1 x 3/2 = 8/3 - 3/2 = 16/6 - 9/6 = 7/6 = 1 1/6
c) (5 x 2/15 + 1/2) x 3/5 = (5/1 x 2/15 + 1/2) x 3/5 = (2/3 + 1/2) x 3/5 = 3(4/6 + 3/6) x 3/5 = 7/6 x 3/5 = 7/10
d) = 11/2 - 3/4 x 6/1 + (2 x 2 x 2) = 11/2 - 9/2 + 8 = 1 + 8 = 9
