Step-by-step Analysis of Each Number:

We’ll look at each number in the circles:

1. 5
- Multiple of 5 → blue

2. 32
- 32 ÷ 2 = 16 → multiple of 2 → green

3. 10
- Multiple of 2 and 5 → also multiple of 10 → red

4. 2
- Multiple of 2 → green

5. 16
- 16 ÷ 2 = 8 → multiple of 2 → green

6. 26
- 26 ÷ 2 = 13 → multiple of 2 → green

7. 45
- 45 ÷ 5 = 9 → multiple of 5 → blue

8. 80
- 80 ÷ 2 = 40 → multiple of 2
- 80 ÷ 5 = 16 → multiple of 5
- 80 ÷ 10 = 8 → multiple of 10 → red

9. 15
- 15 ÷ 5 = 3 → multiple of 5 → blue

10. 75
- 75 ÷ 5 = 15 → multiple of 5 → blue

11. 22
- 22 ÷ 2 = 11 → multiple of 2 → green

12. 55
- 55 ÷ 5 = 11 → multiple of 5 → blue

13. 20
- 20 ÷ 2 = 10 → multiple of 2
- 20 ÷ 5 = 4 → multiple of 5
- 20 ÷ 10 = 2 → multiple of 10 → red

14. 100 (on the left side, not visible in the right image)
- 100 ÷ 2 = 50 → multiple of 2
- 100 ÷ 5 = 20 → multiple of 5
- 100 ÷ 10 = 10 → multiple of 10 → red

How to Solve:

- Look at each number inside the circles.
- Check if it's divisible by:
- 2 → color green
- 5 → color blue
- If divisible by both 2 and 5, i.e., by 10 → color red (overrides others)
- Note: Numbers divisible by 10 are automatically divisible by both 2 and 5, so they get red.

Final Answer:

Color each circle as follows:
- Red: 10, 80, 20, 100
- Blue: 5, 45, 15, 75, 55
- Green: 32, 2, 16, 26, 22
