Let's solve each of the fraction addition problems shown in the image step by step. Each problem is represented both visually and numerically.

Problem 1:
Visual: Two sets of triangles, each divided into 7 equal parts.
- First shape: 4 out of 7 triangles are shaded (pink).
- Second shape: 2 out of 7 triangles are shaded (pink).
- Total shaded: 4 + 2 = 6 out of 7 triangles.
Numerical:
$$
\frac{4}{7} + \frac{2}{7} = \frac{6}{7}
$$
✔ Answer: $ \frac{6}{7} $

Problem 2:
Visual: Two hexagons, each divided into 12 equal parts (like a clock).
- First hexagon: 3 out of 12 parts are shaded (green).
- Second hexagon: 5 out of 12 parts are shaded (green).
- Total shaded: 3 + 5 = 8 out of 12 parts.
Numerical:
$$
\frac{3}{12} + \frac{5}{12} = \frac{8}{12}
$$
Now simplify:
$$
\frac{8}{12} = \frac{2}{3} \quad \text{(dividing numerator and denominator by 4)}
$$
But since the problem shows the answer box as two blanks (numerator and denominator), we can write either $ \frac{8}{12} $ or simplified $ \frac{2}{3} $. However, since the original fractions are not simplified, and the visual shows 8 out of 12, it's acceptable to leave it as $ \frac{8}{12} $ unless simplification is required.
✔ Answer: $ \frac{8}{12} $ or simplified $ \frac{2}{3} $
>
✔ For consistency with the format,
$ \frac{8}{12} $ is appropriate here.

Problem 3:
Visual: Two rectangles, each divided into 10 equal parts (a 2x5 grid).
- First rectangle: 4 out of 10 parts are shaded (orange).
- Second rectangle: 4 out of 10 parts are shaded (orange).
- Total shaded: 4 + 4 = 8 out of 10 parts.
Numerical:
$$
\frac{4}{10} + \frac{4}{10} = \frac{8}{10}
$$
Simplify:
$$
\frac{8}{10} = \frac{4}{5}
$$
Again, depending on whether simplification is expected, but the visual shows 8 out of 10, so $ \frac{8}{10} $ is correct for the diagram.
✔ Answer: $ \frac{8}{10} $ or simplified $ \frac{4}{5} $
>
✔ We'll use $ \frac{8}{10} $ to match the visual representation.

✔ Final Answers:
1. $ \frac{4}{7} + \frac{2}{7} = \boxed{\frac{6}{7}} $
2. $ \frac{3}{12} + \frac{5}{12} = \boxed{\frac{8}{12}} $
3. $ \frac{4}{10} + \frac{4}{10} = \boxed{\frac{8}{10}} $
> 💡 Note: All these are
like fractions (same denominators), so you simply add the numerators and keep the denominator the same.
