Answer 3

To add fractions, you need to have a common denominator. In both expressions you provided, the denominators are already the same, so you can add the numerators directly.

1. Adding 8/99 and 91/99:

The denominators are the same, so you can add the numerators: 8/99 + 91/99 = (8 + 91)/99 = 99/99 = 1

Therefore, 8/99 + 91/99 equals 1.

2. Adding 77/90 and 13/90:

The denominators are the same, so you can add the numerators: 77/90 + 13/90 = (77 + 13)/90 = 90/90 = 1

Therefore, 77/90 + 13/90 equals 1.
