Answer 1

A) 5/3 - 2 - (1/6 - 3/2)
    5/3 - 2 - (1/6 - 9/6)
    5/3 - 2 - (-8/6)
    5/3 - 2 + 8/6 
    5/3 - 2 + 4/3
    9/3 - 2
    9/3 - 6/3 = 3/3 = 1
b) 2 - (5/2 - 3) - 2/5
    2 - (5/2 - 6/2) - 2/5
    2 - (-1/2) - 2/5
    2 - (-5/10) - 4/10
    2 + 5/10 - 4/10
    2 + 1/10 = 20/10 + 1/10 = 21/10 = 2.1
c) 4/3 : (2/5 - 7/5)
    4/3 : (-5/5)
    20/15 : (-15/15)
    300/-225 = -60/45 = -12/9 = -4/3 = -1.333
d) 2 - (4/3 - 5/4) : 2
    2 - (16/12 - 15/12) : 2
    2 - (1/12) : 2
    2 - 1/24
    48/24 - 1/24 = 47/24 = 1.9583
