Step-by-step solutions:

1. $ \frac{6}{8} - \frac{3}{8} = \frac{6 - 3}{8} = \frac{3}{8} $

2. $ \frac{3}{5} - \frac{2}{5} = \frac{3 - 2}{5} = \frac{1}{5} $

3. $ \frac{5}{6} - \frac{4}{6} = \frac{5 - 4}{6} = \frac{1}{6} $

4. $ \frac{3}{4} - \frac{2}{4} = \frac{3 - 2}{4} = \frac{1}{4} $

5. $ \frac{3}{6} - \frac{2}{6} = \frac{3 - 2}{6} = \frac{1}{6} $

6. $ \frac{4}{8} - \frac{2}{8} = \frac{4 - 2}{8} = \frac{2}{8} = \frac{1}{4} $
*(Simplify $ \frac{2}{8} $ by dividing numerator and denominator by 2)*

7. $ \frac{2}{3} - \frac{1}{3} = \frac{2 - 1}{3} = \frac{1}{3} $

8. $ \frac{3}{5} - \frac{1}{5} = \frac{3 - 1}{5} = \frac{2}{5} $

9. $ \frac{4}{6} - \frac{1}{6} = \frac{4 - 1}{6} = \frac{3}{6} = \frac{1}{2} $
*(Simplify $ \frac{3}{6} $ to $ \frac{1}{2} $)*

10. $ \frac{2}{4} - \frac{1}{4} = \frac{2 - 1}{4} = \frac{1}{4} $

11. $ \frac{6}{8} - \frac{4}{8} = \frac{6 - 4}{8} = \frac{2}{8} = \frac{1}{4} $

12. $ \frac{4}{5} - \frac{3}{5} = \frac{4 - 3}{5} = \frac{1}{5} $

13. $ \frac{7}{8} - \frac{6}{8} = \frac{7 - 6}{8} = \frac{1}{8} $

14. $ \frac{4}{6} - \frac{3}{6} = \frac{4 - 3}{6} = \frac{1}{6} $

15. $ \frac{4}{5} - \frac{1}{5} = \frac{4 - 1}{5} = \frac{3}{5} $

16. $ \frac{4}{8} - \frac{3}{8} = \frac{4 - 3}{8} = \frac{1}{8} $

17. $ \frac{3}{6} - \frac{1}{6} = \frac{3 - 1}{6} = \frac{2}{6} = \frac{1}{3} $

18. $ \frac{5}{8} - \frac{2}{8} = \frac{5 - 2}{8} = \frac{3}{8} $

🔍 Explanation:

When subtracting fractions with the same denominator, you only subtract the numerators and keep the denominator unchanged. Then, if possible, simplify the result by dividing both numerator and denominator by their greatest common divisor (GCD).

For example:
$ \frac{4}{6} - \frac{1}{6} = \frac{3}{6} $ → Simplify $ \frac{3}{6} $ to $ \frac{1}{2} $ by dividing both by 3.

This is a foundational skill in fraction arithmetic and helps build understanding for more complex operations later on.
