Percent - Percent means the number of parts in each hundred.

Pupils may make mistakes when writing single-digit percentages as a decimal number (e.g. 3%).
Remind pupils that percentages are recorded as hundredths. Where is the hundredths column in a decimal number? Writing measurements where one unit is a hundredth of another (e.g. number of pence as a percentage of a pound) may help reinforce this.
