Question 9

1. Both fractions have the same denominator.
2. Denominator = (17).
3. Add only the numerators: (4 + 15).
4. (4 + 15 = 19).
5. Keep the denominator the same: (17).
6. ( frac{4}{17} + frac{15}{17} = frac{(4+15)}{17}).
7. ( frac{(4+15)}{17} = frac{19}{17}).

So, the sum is ( frac{19}{17}) (option A).

Note: ( frac{19}{17}) is an improper fraction. As a mixed number it is (1 frac{2}{17}).
