Practice Pie Charts →Proportion Language for Pie Charts
Unlike line graphs, pie charts rarely show time changes. Your main tool is proportion language — fractions, percentages, and comparative phrases.
- Fractions: nearly half, just over a quarter, approximately one third
- Percentages: 48%, around 25%, exactly 12%
- Superlatives: the largest segment, the smallest proportion, the dominant category
- Comparisons: twice as much as, roughly three times higher than, slightly more than
Example: Housing accounted for the largest share of expenditure at 35%, more than double the proportion spent on food (15%).
Comparing Two Pie Charts
Tasks often show two pie charts (e.g., two countries or two years). Your overview should identify the most significant similarity or difference between the two charts before diving into detail.

Common Errors in Pie Chart Tasks
Many students simply list percentages without drawing any comparison, which limits the band score to 5–6.
- Avoid: 'Housing is 35%. Food is 15%. Transport is 20%.'
- Instead: Group similar segments and make comparisons explicit
- Always check that your proportions add up to 100%
