Answer 2

Let's break down the equation step by step:

1 + 3/15: To add 1 and 3/15, we need to find a common denominator. The denominator of 15 is already common, so we can simply add the numerators: 1 + 3 = 4. Therefore, 1 + 3/15 equals 4/15.

1 - 11/15: Similarly, we need to find a common denominator, which is 15. The equation becomes: 15/15 - 11/15. Subtracting the numerators gives us: 15 - 11 = 4. Thus, 1 - 11/15 equals 4/15.

16/15 - 1: Here, we have a mixed number and a whole number. To simplify this, we can rewrite 1 as 15/15. The equation then becomes: 16/15 - 15/15. Subtracting the numerators gives us: 16 - 15 = 1. Thus, 16/15 - 1 equals 1/15.

8/15 + 1: We have a fraction and a whole number. We can rewrite 1 as 15/15 to find a common denominator: 8/15 + 15/15. Adding the numerators gives us: 8 + 15 = 23. Therefore, 8/15 + 1 equals 23/15.

In summary: 1 + 3/15 = 4/15 1 - 11/15 = 4/15 16/15 - 1 = 1/15 8/15 + 1 = 23/15
