What do these numbers mean?
- A percentage means parts per hundred: 25% = 0.25. A share compares a part with a whole; percentage change compares the difference with the absolute starting value.
- In decimal numbers, commas separate thousands and a dot separates decimals: 1,234.5 = 1234 + 0.5. ×10^3 means multiply by 1000; ×10^-3 means divide by 1000. Display rounding can make tiny differences between shown totals.

Part of the whole
- Part

How this is worked out
- 15 ÷ 100 = 0.15.
- 0.15 × 240 = 36.
Percent change is measured against the first value.
