One Quarter Three Ways
Age 11 Maths
A fraction, a decimal and a percentage can all describe exactly the same amount. Here 1/4, 0.25 and 25% each mean one part out of four equal parts.
Step by step
- Badge 1 sits on the single dark square of the chocolate bar: 1 of 4 equal squares, written 1/4.
- Badge 2 sits on the glass, where the juice stops at the first of four marks, written 0.25.
- Badge 3 sits on the teal section of the folded ribbon, one of its four equal parts, written 25%.
Examples
- A jacket with 25% off costs a quarter less than the ticket price.
- A measuring jug filled to 0.25 litres holds a quarter of a litre.
Key takeaways
- 1/4, 0.25 and 25% are three names for the same amount.
- Divide the top number by the bottom one to get the decimal, then multiply by 100 for the percentage.
