Answer 2

To solve this expression, you need to perform the addition and subtraction of the fractions step by step. Here's how you can do it:

1. Add the first two fractions: 1 2/15 + 2 7/15

   To add these fractions, you need to first add the whole numbers and then add the fractions separately.

   Whole numbers: 1 + 2 = 3 Fractions: 2/15 + 7/15 = 9/15 = 3/5

   So, 1 2/15 + 2 7/15 = 3 3/5

2. Subtract the third fraction: 3 3/5 - 2 8/15

   Again, subtract the whole numbers and fractions separately.

   Whole numbers: 3 - 2 = 1 Fractions: 3/5 - 8/15

   To subtract fractions with different denominators, you need to find a common denominator. The least common multiple (LCM) of 5 and 15 is 15.

   Convert fractions to have a common denominator of 15: 3/5 = 9/15 8/15 (already in terms of 15)

   Now, subtract the fractions: 9/15 - 8/15 = 1/15

   So, 3 3/5 - 2 8/15 = 1 1/15

Therefore, the result of the expression 1 2/15 + 2 7/15 - 2 8/15 is 1 1/15.
