1. 93.9°
Total = 23. Yellow fraction = 6/23. 6/23 × 360° = 93.9°.
2. 77.8°
Total = 37. Red fraction = 8/37. 8/37 × 360° = 77.8°.
3. 115.2°
Total = 25. Green fraction = 8/25. 8/25 × 360° = 115.2°.
4. 112.5°
Total = 32. Red fraction = 10/32. 10/32 × 360° = 112.5°.
5. 72°
Total = 35. Red fraction = 7/35. 7/35 × 360° = 72°.
6. 50°
Total = 36. Green fraction = 5/36. 5/36 × 360° = 50°.

Worked examples
In a survey: Red 10, Blue 11, Green 11, Yellow 5. In a pie chart, what angle does Blue get?
- Total = 37.
- Blue fraction = 11/37.
- 11/37 × 360° = 107°.
- Answer: 107°
In a survey: Red 11, Blue 9, Green 15, Yellow 3. In a pie chart, what angle does Blue get?
- Total = 38.
- Blue fraction = 9/38.
- 9/38 × 360° = 85.3°.
- Answer: 85.3°
In a survey: Red 10, Blue 10, Green 3, Yellow 4. In a pie chart, what angle does Yellow get?
- Total = 27.
- Yellow fraction = 4/27.
- 4/27 × 360° = 53.3°.
- Answer: 53.3°

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.
