The sum of 7/10 and 4/15 = 29/30
11/15
4/20 + 15/20 = 19/20
The sum of the first 5 numbers is 15. 1+2+3+4+5=15
2/5 = 6/15 + 4/15 = 10/15 = 2/3
The sum of 2/6 and 4/5 = 1 2/15
The sum of 15/16 and 1/4 is 1 3/16
The sum of 7/10 and 4/15 = 29/30
The sum of 4/20 and 2/13 is 23/65
11/15
4/20 + 15/20 = 19/20
If 1,2,3,4,5, is a sequence, then the sum is 1+2+3+4+5 = 15
4/5 + 2/15 = 14/15
The sum of the first 5 numbers is 15. 1+2+3+4+5=15
2/5 = 6/15 + 4/15 = 10/15 = 2/3
2 3 over 20
15/2*4 = 30
