The answer is... 1 whole and 15 over 30
6/10 + 3/9 = 3/5 + 1/3 = 9/15 + 5/15 = 14/15
It is 11 over 15.
9/10 + 6/10 = 15/10 (Which can be written as 3/2 or 11/2)
30
9/10 + 3/5 = 9/10 + 6/10 = 15/10 = 3/2 or 11/2
3/5 + 9/10 = 6/10 + 9/10 = 15/10 = 3/2 or 11/2
15/20 or 3/4
9 over 10 + 5 over 6 = 27 over 30 + 25 over 30 = 52 / 30 = 26/15 = 1 11/15
It is: 2/15 plus 3/9 = 7/15
(9 + 15) / (15 - 10) = 24 / 5 = 4.8
9/30 + -26/30 = -17/30
