Show Answer Key & Explanations Step-by-step solution for: Fractions online exercise for Grade 3
Let's solve each shape one by one and write the fraction that represents the shaded area of each shape. The general rule is:

> Fraction = (Number of shaded parts) / (Total number of equal parts)

---

Row 1



1. Circle divided into 4 equal parts, 2 shaded (blue):
- Shaded: 2
- Total: 4
- Fraction: 2/4 = 1/2

2. Star divided into 5 equal points, 1 shaded (yellow):
- Shaded: 1
- Total: 5
- Fraction: 1/5

3. Rectangle divided into 3 equal horizontal parts, 1 shaded (blue):
- Shaded: 1
- Total: 3
- Fraction: 1/3

4. Hexagon divided into 4 equal parts, 1 shaded (green):
- Wait — a hexagon has 6 sides, but this is divided into 4 equal parts, not 6.
- Actually, it looks like it's split into 4 sections: two on top, two on bottom? But visually, it’s split into 4 equal regions (like a square-like division), with one green.
- So:
- Shaded: 1
- Total: 4
- Fraction: 1/4
