🔹 Step-by-step Solutions:

#### 1. $ \frac{7}{9} - \frac{1}{9} $
- Subtract numerators: $ 7 - 1 = 6 $
- Keep denominator: $ 9 $
- Answer: $ \frac{6}{9} $

✔ Simplify: $ \frac{6}{9} = \frac{2}{3} $

#### 2. $ \frac{4}{6} - \frac{1}{6} $
- $ 4 - 1 = 3 $
- Denominator stays 6
- Answer: $ \frac{3}{6} $

✔ Simplify: $ \frac{3}{6} = \frac{1}{2} $

#### 3. $ \frac{6}{8} - \frac{1}{8} $
- $ 6 - 1 = 5 $
- Denominator: 8
- Answer: $ \frac{5}{8} $

✔ Already simplified.

📝 Summary:

To subtract fractions with the same denominator:
1. Subtract the numerators.
2. Keep the denominator unchanged.
3. Simplify the result if possible.

This method works because both fractions represent parts of the same whole (same denominator), so we can directly compare or subtract their parts.
