7/8 + 9/10 + 6/5

To add fractions with different denominators, you need to find a common denominator. In this case, the common denominator is 40.

Now, convert each fraction to this common denominator:

7/8 = (7/8) * (5/5) = 35/40
9/10 = (9/10) * (4/4) = 36/40
6/5 = (6/5) * (8/8) = 48/40

Now, add the converted fractions together:
35/40 + 36/40 + 48/40 = (35 + 36 + 48)/40 = 119/40

Therefore, 7/8 + 9/10 + 6/5 = 119/40.
