Show answers and working
1. 40°
Total = 27. Green fraction = 3/27. 3/27 × 360° = 40°.
2. 88°
Total = 45. Green fraction = 11/45. 11/45 × 360° = 88°.
3. 30.9°
Total = 35. Red fraction = 3/35. 3/35 × 360° = 30.9°.
4. 120°
Total = 36. Red fraction = 12/36. 12/36 × 360° = 120°.
5. 90°
Total = 28. Green fraction = 7/28. 7/28 × 360° = 90°.
6. 60°
Total = 24. Blue fraction = 4/24. 4/24 × 360° = 60°.

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.
