Show answers and working
1. 24.8°
Total = 29. Red fraction = 2/29. 2/29 × 360° = 24.8°.
2. 144°
Total = 30. Green fraction = 12/30. 12/30 × 360° = 144°.
3. 22.5°
Total = 32. Green fraction = 2/32. 2/32 × 360° = 22.5°.
4. 108°
Total = 40. Blue fraction = 12/40. 12/40 × 360° = 108°.
5. 108°
Total = 30. Green fraction = 9/30. 9/30 × 360° = 108°.
6. 41.5°
Total = 26. Yellow fraction = 3/26. 3/26 × 360° = 41.5°.
7. 111.4°
Total = 42. Red fraction = 13/42. 13/42 × 360° = 111.4°.
8. 78.8°
Total = 32. Red fraction = 7/32. 7/32 × 360° = 78.8°.

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.
