-15
(28 + 76)/13 = 104/13 = 8
-13 and -15
The integers are 13 and 15.
=The Two numbers are 41 and 13.=
The sum is 28+38 = 66
6/7 = 24/28, 1/4 = 7/28 so sum is 31/28 ie 13/28.
call the first number x. The second number would be x + 2 (as they're consecutive odd numbers). The sum of both numbers would be x + x + 2 = 28, or 2x + 2 = 28. This can be evaluated to 2x = 26, x = 13. The first number would be 13, the second 15, 13 + 15 = 28.
The sum of 5/7 and 3/4 = 1 13/28
The sum is 93.
To compare the two pairs of numbers, we can look at their sums. The sum of 13 and 15 is 28, while the sum of 22 and 25 is 47. Therefore, 22 and 25 is the bigger pair.
