🔹 Part 1: Select the correct fraction

We'll go row by row.

---

#### Row 1
- Shape: A rectangle divided into 10 small squares (2 rows × 5 columns).
- Shaded squares: 5 (pink)
- Total squares: 10
- Fraction: $ \frac{5}{10} $

✔ Correct answer: $ \frac{5}{10} $

---

#### Row 2
- Shape: Rectangle divided into 6 equal vertical strips.
- Shaded: 2 yellow strips
- Total: 6
- Fraction: $ \frac{2}{6} $

✔ Correct answer: $ \frac{2}{6} $

---

#### Row 3
- Shape: 2×2 grid = 4 squares total.
- Shaded: 2 blue squares
- Total: 4
- Fraction: $ \frac{2}{4} $

✔ Correct answer: $ \frac{2}{4} $

---

#### Row 4
- Shape: 3 rows × 3 columns = 9 squares
- Shaded: 4 purple squares
- Total: 9
- Fraction: $ \frac{4}{9} $

✔ Correct answer: $ \frac{4}{9} $

---

#### Row 5
- Shape: 3 equal horizontal rectangles (like a bar)
- Shaded: 1 green rectangle
- Total: 3
- Fraction: $ \frac{1}{3} $

✔ Correct answer: $ \frac{1}{3} $

---

#### Row 6
- Shape: Rectangle divided into 6 horizontal bars (3 full rows, each split into 2 parts → 6 parts total)
- Shaded: 4 blue bars
- Total: 6
- Fraction: $ \frac{4}{6} $

✔ Correct answer: $ \frac{4}{6} $

---

✔ Summary of Part 1 Answers:

| Row | Correct Fraction |
|-----|------------------|
| 1 | $ \frac{5}{10} $ |
| 2 | $ \frac{2}{6} $ |
| 3 | $ \frac{2}{4} $ |
| 4 | $ \frac{4}{9} $ |
| 5 | $ \frac{1}{3} $ |
| 6 | $ \frac{4}{6} $ |

---

🔹 Part 2: Write the fraction for the shaded part

Now we need to write the fraction for each shape.

---

#### Shape 1: Rectangle divided into 5 vertical strips
- Shaded: 2 purple strips
- Total: 5
- Fraction: $ \frac{2}{5} $

✔ Answer: $ \frac{2}{5} $

---

#### Shape 2: Regular hexagon divided into 6 equal triangles
- Shaded: 4 green triangles
- Total: 6
- Fraction: $ \frac{4}{6} $ → can be simplified to $ \frac{2}{3} $, but since it's asking for the shaded part as shown, we use $ \frac{4}{6} $ unless simplification is required.

But typically in such worksheets, simplest form is expected.

So: $ \frac{4}{6} = \frac{2}{3} $

✔ Answer: $ \frac{2}{3} $ (or $ \frac{4}{6} $ if not simplified — but best to simplify)

---

#### Shape 3: Square divided into 4 smaller squares
- Shaded: 2 yellow squares
- Total: 4
- Fraction: $ \frac{2}{4} = \frac{1}{2} $

✔ Answer: $ \frac{1}{2} $

---

#### Shape 4: Triangle divided into 2 equal right triangles
- Shaded: 1 blue triangle
- Total: 2
- Fraction: $ \frac{1}{2} $

✔ Answer: $ \frac{1}{2} $

---

✔ Summary of Part 2 Answers:

1. $ \frac{2}{5} $
2. $ \frac{2}{3} $ (or $ \frac{4}{6} $)
3. $ \frac{1}{2} $
4. $ \frac{1}{2} $

---

🟩 Final Answer Key:

#### Part 1 – Select the correct fraction:
1. $ \frac{5}{10} $

3. $ \frac{2}{4} $
4. $ \frac{4}{9} $
5. $ \frac{1}{3} $
6. $ \frac{4}{6} $

#### Part 2 – Write the fraction:
1. $ \frac{2}{5} $
2. $ \frac{2}{3} $
3. $ \frac{1}{2} $
4. $ \frac{1}{2} $
