These 3 are 3 different ways of expressing a **Proportion** of something.

To convert one of these proportions to another is simple as you:

Divide you fraction top from bottom e.g. 1/2 = 1 divided by 2 = 0.5 to a decimal

Times the decimal by 100 will make the percentage e.g. 0.5 x 100 = 50%

The opposite way to do this is:

divide the percentage by 100 to get the decimal e.g. 50% divided by 100 = 0.5 to a decimal

To convert a decimal to a fraction, look at these examples to get the pattern:
