Worked examples
In a survey: Red 2, Blue 11, Green 10, Yellow 9. In a pie chart, what angle does Green get?
- Total = 32.
- Green fraction = 10/32.
- 10/32 × 360° = 112.5°.
- Answer: 112.5°

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.
