11)
6 - 1/3 = 18/3 - 1/3 = 17/3

12)
1/3 × 2 = 2/3

13)
1/4 + 2 - 1/3 = 3/12 + 24/ 12 - 4/12
= 23/12

14)
5/2 - 1/2 + 1/3 = 4/2 + 1/3
= 12/6 + 2/6 = 14/6 = 7/3

15)
3 - 1/3 + 1/2 - 4 = 18/6 - 2/6 + 3/6 - 24/6
= 16/6 - 21/6
= -5/6

16)
8/4 = 16/x
2x = 16
x = 8

17)
10/2 = x/6
x = 5 × 6
x = 30

18)
2x - 8 = 0
2x = 8
x = 4
