Percentages are used in two main ways in everyday life:

1.As operators

In many real life situations you find a percentage of an amount. For example, if you buy something at 30% discount you pay 70% of the usual price.

70% operates on the usual price, e.g. 70% of $60 is $42

2. As proportions

Percentages are often used to compare two or more proportions. For example, to compare two shooters in a netball game you might convert the statistics into percentages.

Selma gets 32 out of 40 shots so her shooting percentage is 80%

Niki gets 33 out of 44 shots so her percentage is 75%
