We can take the information in a given ratio and use it to write the percentage that each part of the ratio represents. For example, if the ratio of the number of boys to the number of girls in a class is 2:3 then we can see that 2 fifths of the students are boys and 3 fifths are girls. 2 fifths is equal to 40% and 3 fifths is equal to 60%. Therefore 40% of the students are boys and 60% are girls. A percentage must have a percent sign.
The same idea can be applied to 3 part ratios and ratios with any number of parts. For example if the ratio of yellow counters:red counters:blue counters in a bag is 2:3:5 then the fractions would be frac{2}{10} : frac{3}{10} : frac{5}{10} and the percentages would be 20% : 30% : 50%.
Looking forward, students can then progress to additional ratio worksheets and other ratio and proportion worksheets, for example a ratio worksheet or a simplifying ratios worksheet.
For more teaching and learning support on Ratio and Proportion our GCSE maths lessons provide step by step support for all GCSE maths concepts.
