Answer 2

To solve the expression, we need to find a common denominator for the fractions and then perform the operations. The common denominator for 9, 11, and 99 is 99.

2/9 + 7/11 - 10/99

Step 1: Convert all fractions to have a denominator of 99.

(2/9) * (11/11) = 22/99

(7/11) * (9/9) = 63/99

10/99

Now, the expression becomes:

(22/99) + (63/99) - (10/99)
