To solve this expression, you need to add the two fractions together. Here's how you can do it step by step:

1. Make sure that the denominators (the numbers at the bottom of the fractions) are the same. In this case, the denominators are already the same, so we don't need to do anything.

2. Add the numerators (the numbers at the top of the fractions) together while keeping the denominator the same. So, 17 + 5 = 22.

3. Write the sum of the numerators (22) over the common denominator (18). The result is 22/18.

4. Simplify the fraction, if possible. In this case, you can divide the numerator and the denominator by their greatest common divisor, which is 2. So, 22/18 simplifies to 11/9.

Therefore, 17/18 + 5/18 is equal to 11/9.
