Answer 1

A)
x=9 1/2 - 4 1/3
x=9 3/6 - 4 2/6
x=5 1/6
b)
5 5/6 - 4 1/3 = x
5 5/6 - 4 2/6 = x
x = 1 1/2
c)
x = 9 2/7 - 6 2/5 
x = 9 10/35 - 6 14/35
x = 2 31/35
d)
16 1/3 - 12 5/8 = x
16 8/24 - 12 15/24 = x
x = 3 18/24
x = 3 3/4
e)
x = 6 2/7 - 3 5/8
x = 6 16/56 - 3 35/56
x = 2 37/56
f)
x = 2 4/5 + 7 5/12
x = 2 48/60 + 7 25/60
x = 10 13/60
