A percentage is like a special kind of fraction in KS3 Maths. When you spot the percentage sign (%), it means you're dealing with hundredths. Being confident with percentages is important, and this quiz is here to help you understand the parts of whole numbers represented by percentages.
A percentage is a fraction with a denominator of 100. So, 44% is the same as 44⁄100, and 130% is 130⁄100. Percentages pop up a lot in daily life, making things much easier when you get the hang of them!

One way to work this out is to divide 240g by 20 to find 5% then multiply your answer by 3 for 15%
