Fractions, Decimals and Percentages
- Fractions, decimals and percentages are all different ways to represent a quantity as part of a whole.
2. They can all be converted into each of the other forms and still represent the same amount – this means they are
3. These are some common equivalents that you should know.
1/100 = 0.01 = 1%
1/10 = 0.1 = 10%
½ = 0.5 = 50%
¼ = 0.25 = 25%
1/5 = 0.2 = 20%
- Hopefully, you will be able to use these facts to help you find out the answers for equivalents of other fractions, decimals and percentages.
Example 1:
Let’s say we want to find out what ¾ is as a percentage.
We already know that ¼ is 25% – ¾ must be three times bigger than this.
25% x 3 = 75%
Converting between fractions, decimals and percentages using a calculator is quite simple if you know what to do.
- You can convert a fraction to a decimal by dividing the numerator by the denominator
2. You can convert a decimal to a percentage by multiplying it by 100.
3. You can convert a percentage to a decimal by dividing it by 100.
4. You can convert a percentage to a fraction by writing the number over a denominator of 100.
