1. 40°
Total = 27. Green fraction = 3/27. 3/27 × 360° = 40°.
2. 104.5°
Total = 31. Red fraction = 9/31. 9/31 × 360° = 104.5°.
3. 37.9°
Total = 19. Yellow fraction = 2/19. 2/19 × 360° = 37.9°.
4. 99.3°
Total = 29. Yellow fraction = 8/29. 8/29 × 360° = 99.3°.
5. 37.9°
Total = 38. Yellow fraction = 4/38. 4/38 × 360° = 37.9°.

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.
