1/3 = 2/6 + 1/6 = 3/6 or 1/2
1/3 + 3/6 = 2/6 + 3/6 = 5/6
1/6 + 3/6 = 4/6 = 2/3
3 over 6 is equivalent to 1 over 2.
(1/3) x (2/2) x (3/6) = 1/6
1/6 + 3/6 = 4/6 = 2/3
1/6 + 3/18 = 1/3
1/6 + 1/3 = 1/6 + 2/6 = 3/6 = 1/2
2/3 + 1/6 + 1/6 = 1
6/6 or 1
5/6 - (3/1)/6 = 5/6 - 3/6 = 2/6 = 1/3
6/9 - 1/3 = 2/3 - 1/3 = 1/3
