Show answers and working
1. 41.5°
Total = 26. Red fraction = 3/26. 3/26 × 360° = 41.5°.
2. 85.7°
Total = 42. Red fraction = 10/42. 10/42 × 360° = 85.7°.
3. 36°
Total = 30. Red fraction = 3/30. 3/30 × 360° = 36°.
4. 130.9°
Total = 33. Yellow fraction = 12/33. 12/33 × 360° = 130.9°.
5. 116.5°
Total = 34. Yellow fraction = 11/34. 11/34 × 360° = 116.5°.
6. 54°
Total = 40. Blue fraction = 6/40. 6/40 × 360° = 54°.
7. 95.3°
Total = 34. Red fraction = 9/34. 9/34 × 360° = 95.3°.
8. 69.7°
Total = 31. Red fraction = 6/31. 6/31 × 360° = 69.7°.
9. 52.9°
Total = 34. Yellow fraction = 5/34. 5/34 × 360° = 52.9°.
10. 64.3°
Total = 28. Green fraction = 5/28. 5/28 × 360° = 64.3°.
11. 72°
Total = 30. Yellow fraction = 6/30. 6/30 × 360° = 72°.

Worked examples
In a survey: Red 14, Blue 12, Green 5, Yellow 9. In a pie chart, what angle does Yellow get?
- Total = 40.
- Yellow fraction = 9/40.
- 9/40 × 360° = 81°.
- Answer: 81°
In a survey: Red 4, Blue 8, Green 3, Yellow 12. In a pie chart, what angle does Red get?
- Total = 27.
- Red fraction = 4/27.
- 4/27 × 360° = 53.3°.
- Answer: 53.3°
In a survey: Red 9, Blue 14, Green 14, Yellow 6. In a pie chart, what angle does Blue get?
- Total = 43.
- Blue fraction = 14/43.
- 14/43 × 360° = 117.2°.
- Answer: 117.2°

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.
