1 + 30 + 2 + 3 + 5 + 6 + 10 + 15 = 72
7 and 10/15 + 2 and 12/15 = 9 and 22/15 = 10 and 7/15
1/5 = 3/15 2/3 = 10/15 3/15 + 10/15 = 13/15
2/5 = 6/15 + 4/15 = 10/15 = 2/3
2/3+1/5=10/15+3/15=(10+3)/15=13/15
15 + 15 + (10 * (1 / 2)) + (10 * (1 / 2)) = 40

The answer is 27. 10+15=25. 25+2=27.

1 + 30 + 2 + 3 + 5 + 6 + 10 + 15 = 72

7 and 10/15 + 2 and 12/15 = 9 and 22/15 = 10 and 7/15
8/10 plus 2/6 = 17/15 or 1 and 2/15
1/5 = 3/15 2/3 = 10/15 3/15 + 10/15 = 13/15
2/5 = 6/15 + 4/15 = 10/15 = 2/3
2/3+1/5=10/15+3/15=(10+3)/15=13/15
