Converting fractions to percentages is easy if you know a few handy tips. Here are five simple ways for Year 7 students to learn this skill:
What is a Percentage?
A percentage is just a way to show a fraction out of 100. To change a fraction into a percentage, you can use this formula:
Percentage = (Numerator ÷ Denominator) × 100
Simplifying Fractions
Before you turn a fraction into a percentage, see if you can simplify it. For example, the fraction 8/32 can be simplified to 1/4. This makes it easier to convert:
1/4 × 100 = 25%
Know Common Fractions
It helps to know some common fractions and what they equal as percentages:
Cross-Multiplication
For harder fractions, you can use cross-multiplication. For instance, with 3/5, set up this equation:
3 × 100 = 300
Now divide by 5:
300 ÷ 5 = 60%
Convert to Decimal First
If you're okay with decimals, change the fraction into a decimal first. For example, 3/4 = 0.75, then multiply by 100 to get the percentage:
0.75 × 100 = 75%
Using these simple methods will help you quickly and easily change fractions into percentages!
