Let’s solve each problem step by step. When adding fractions with the same denominator (the bottom number), you just add the numerators (the top numbers) and keep the denominator the same.

---

1.
$\frac{3}{7} + \frac{3}{7}$
Add tops: 3 + 3 = 6
Keep bottom: 7
→ $\frac{6}{7}$

2.
$\frac{2}{5} + \frac{1}{5}$
2 + 1 = 3
→ $\frac{3}{5}$

3.
$\frac{2}{9} + \frac{5}{9}$
2 + 5 = 7
→ $\frac{7}{9}$

4.
$\frac{1}{6} + \frac{4}{6}$
1 + 4 = 5
→ $\frac{5}{6}$

5.
$\frac{1}{4} + \frac{2}{4}$
1 + 2 = 3
→ $\frac{3}{4}$

6.
$\frac{1}{3} + \frac{1}{3}$
1 + 1 = 2
→ $\frac{2}{3}$

7.
$\frac{5}{7} + \frac{1}{7}$
5 + 1 = 6
→ $\frac{6}{7}$

8.
$\frac{5}{12} + \frac{6}{12}$
5 + 6 = 11
→ $\frac{11}{12}$

9.
$\frac{3}{5} + \frac{1}{5}$
3 + 1 = 4
→ $\frac{4}{5}$

10.
$\frac{3}{8} + \frac{4}{8}$
3 + 4 = 7
→ $\frac{7}{8}$

All answers are already in simplest form — no need to reduce further!
