### Instruction: Find $\frac{7}{17} - \frac{4}{51}$. Reduce your answer to simplest form.### Response: To subtract fractions, I need to have a common denominator.
The least common multiple of 17 and 51 is 51, so I will multiply the first fraction by $\frac{3}{3}$ to get the same denominator.
This gives me $\frac{21}{51} - \frac{4}{51}$.
Now I can subtract the numerators and keep the denominator.
This gives me $\frac{21 - 4}{51} = \frac{17}{51}$.
I can simplify this fraction by dividing both the numerator and denominator by 17.
This gives me $\frac{1}{3}$.
