Let’s solve each pair of circles step by step.
We need to:
1. Write the fraction for the shaded part of each circle.
2. Compare the two fractions using >, <, or =.

First Pair (Top Left):
Left circle: Divided into 5 equal parts, 2 are shaded →
2/5
Right circle: Divided into 10 equal parts, 3 are shaded →
3/10
Compare 2/5 and 3/10.
Convert 2/5 to tenths:
2/5 = 4/10
Now compare 4/10 and 3/10 → 4/10 > 3/10
So:
2/5 > 3/10
---
Second Pair (Top Right):
Left circle: Divided into 3 equal parts, 2 are shaded →
2/3
Right circle: Divided into 6 equal parts, 4 are shaded →
4/6
Simplify 4/6 → divide numerator and denominator by 2 →
2/3
So:
2/3 = 4/6
---
Third Pair (Middle Left):
Left circle: Divided into 8 equal parts, 2 are shaded →
2/8
Right circle: Divided into 3 equal parts, 1 is shaded →
1/3
Compare 2/8 and 1/3.
Simplify 2/8 → 1/4
Now compare 1/4 and 1/3.
Think: Which is bigger? A piece cut into 4 parts vs. a piece cut into 3 parts — the 1/3 piece is bigger.
Or use common denominator:
1/4 = 3/12
1/3 = 4/12
→ 3/12 < 4/12 → so 1/4 < 1/3
Thus:
2/8 < 1/3
---
Fourth Pair (Middle Right):
Left circle: Divided into 2 equal parts, 1 is shaded →
1/2
Right circle: Divided into 8 equal parts, 3 are shaded →
3/8
Compare 1/2 and 3/8.
Convert 1/2 to eighths: 1/2 = 4/8
Now compare 4/8 and 3/8 → 4/8 > 3/8
So:
1/2 > 3/8
---
Fifth Pair (Bottom Left):
Left circle: Divided into 4 equal parts, 2 are shaded →
2/4
Right circle: Divided into 8 equal parts, 5 are shaded →
5/8
Simplify 2/4 → 1/2
Compare 1/2 and 5/8.
Convert 1/2 to eighths: 1/2 = 4/8
Now compare 4/8 and 5/8 → 4/8 < 5/8
So:
2/4 < 5/8
---
Sixth Pair (Bottom Right):
Left circle: Divided into 6 equal parts, 3 are shaded →
3/6
Right circle: Divided into 2 equal parts, 1 is shaded →
1/2
Simplify 3/6 → 1/2
So:
3/6 = 1/2
---
Final Answer:
2/5 > 3/10
2/3 = 4/6
2/8 < 1/3
1/2 > 3/8
2/4 < 5/8
3/6 = 1/2
