Show answers and working
1. 120°
Total = 12. Yellow fraction = 4/12. 4/12 × 360° = 120°.
2. 40°
Total = 27. Green fraction = 3/27. 3/27 × 360° = 40°.
3. 64.3°
Total = 28. Yellow fraction = 5/28. 5/28 × 360° = 64.3°.
4. 110°
Total = 36. Red fraction = 11/36. 11/36 × 360° = 110°.
5. 117.2°
Total = 43. Blue fraction = 14/43. 14/43 × 360° = 117.2°.
6. 58.6°
Total = 43. Green fraction = 7/43. 7/43 × 360° = 58.6°.
7. 128.6°
Total = 28. Green fraction = 10/28. 10/28 × 360° = 128.6°.
8. 124.1°
Total = 29. Red fraction = 10/29. 10/29 × 360° = 124.1°.
9. 168.8°
Total = 32. Yellow fraction = 15/32. 15/32 × 360° = 168.8°.
10. 99.3°
Total = 29. Blue fraction = 8/29. 8/29 × 360° = 99.3°.
11. 92.9°
Total = 31. Green fraction = 8/31. 8/31 × 360° = 92.9°.

Total = 31. Green fraction = 3/31. 3/31 × 360° = 34.8°.
Worked examples
In a survey: Red 12, Blue 4, Green 6, Yellow 2. In a pie chart, what angle does Blue get?
- Total = 24.
- Blue fraction = 4/24.
- 4/24 × 360° = 60°.
- Answer: 60°
In a survey: Red 2, Blue 14, Green 9, Yellow 13. In a pie chart, what angle does Green get?
- Total = 38.
- Green fraction = 9/38.

Common mistakes
What learners typically get wrong, and how to fix it.
Uses 100 instead of 360 for pie-chart angles.
Correction: A full circle is 360°.
Forgets to find the total first.
Correction: Add all frequencies before working out fractions.
Teacher tips
- · Have pupils check that all angles add to 360°.
Parent tips
- · Look at charts in the news and ask what they show.
Real-life applications
- · News infographics, survey results.
