To answer this question, first find a common multiple of 3 and 5. Because 5*3=15, multiply 3/5 by 3/3 (one) to get 9/15. Now just add 9/15+1/15 to get 10/15, which can be reduced to 2/3.
Hope this helps!
3 1 - + - 5 3 9 5 - + - 15 15 14 - 15
2/3 + 1/5 = 10/15 + 3/15 = 13/15
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
The sum of -1/15 and -3/5 is -2/3
3 over 15 = 1 over 5
1/5 + 1/3 = 3/15 + 5/15 = 8/15 your answer is 8/15
3 1 - + - 5 3 9 5 - + - 15 15 14 - 15
2/3 + 1/5 = 10/15 + 3/15 = 13/15
14/15
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
2/5
It's 7 over 15.
The sum of -1/15 and -3/5 is -2/3
(1/3) + (4/10) = (5/15) + (6/15) = 11/15
1 over 5 plus 3 = 31/5 or 16/15
