7/18
1/6 + 3/18 = 1/3
2/3 + 1/9 + 5/6 = 12/18 + 2/18 + 15/18 = 29/18 = 111/18
1/9 = 2/18 3/6 = 9/18 2/18 + 9/18 = 11/18
1/5 + 6/18 = 1/5 + 1/3 = 3/15 + 5/15 = 8/15
3/4 + 1/24 = 18/24 + 1/24 = 19/24
lowest common denominator is 18 2/9 + 1/6 = 4/18 + 3/18 = 7/18
2/3 + 1/6 = 15/18 which simplifies to 5/6
5/6 + 9/1 + 2/3 --> 15/18 + 162/18 + 12/18 = 189/18 --> 10 9/18 --> 10 1/2
That's a total of 18.
3/5 + 1/6 = 18/30 + 5/30 = 23/30
It is: 1/3 plus 1/3 = 2/3
1/3 × 18 = 1/3 × 18/1 = (1×18)/(3×1) = 18/3 = 18 ÷ 3 = 6.
