2/5 = 6/15 + 4/15 = 10/15 = 2/3
1/5 = 3/15 2/3 = 10/15 3/15 + 10/15 = 13/15
2/3+1/5=10/15+3/15=(10+3)/15=13/15
It is: 13/30
-15/10 + 16/10 = 1/10
2/5 = 6/15 + 4/15 = 10/15 = 2/3
1/5 = 3/15 2/3 = 10/15 3/15 + 10/15 = 13/15
2/3+1/5=10/15+3/15=(10+3)/15=13/15
It is: 13/30
-15/10 + 16/10 = 1/10
2/3 + 1/5 = 10/15 + 3/15 = 13/15
9/10 + 6/10 = 15/10 (Which can be written as 3/2 or 11/2)
15 + 15 + (10 * (1 / 2)) + (10 * (1 / 2)) = 40
42
3/5 + 9/10 = 6/10 + 9/10 = 15/10 = 3/2 or 11/2
9/10 + 3/5 = 9/10 + 6/10 = 15/10 = 3/2 or 11/2
It is: 2/15 plus 3/9 = 7/15
