  1. 1. 116.5°

    Total = 34. Green fraction = 11/34. 11/34 × 360° = 116.5°.

  2. 2. 112°

    Total = 45. Red fraction = 14/45. 14/45 × 360° = 112°.

  3. 3. 104.2°

    Total = 38. Green fraction = 11/38. 11/38 × 360° = 104.2°.

  4. 4. 101.7°

    Total = 46. Green fraction = 13/46. 13/46 × 360° = 101.7°.

  5. 5. 53.3°

    Total = 27. Green fraction = 4/27. 4/27 × 360° = 53.3°.

  6. 6. 46.5°

    Total = 31. Red fraction = 4/31. 4/31 × 360° = 46.5°.

  7. 7. 75°

    Total = 24. Yellow fraction = 5/24. 5/24 × 360° = 75°.

  8. 8. 140°

    Total = 18. Blue fraction = 7/18. 7/18 × 360° = 140°.

  9. 9. 61.5°

    Total = 41. Blue fraction = 7/41. 7/41 × 360° = 61.5°.

  10. 10. 85.3°

    Total = 38. Green fraction = 9/38. 9/38 × 360° = 85.3°.

  11. 11. 46.5°

    Total = 31. Green fraction = 4/31. 4/31 × 360° = 46.5°.

  12. 12. 151°

    Total = 31. Blue fraction = 13/31. 13/31 × 360° = 151°.

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.
