How to work out percentages

To work out the percentage of any number, follow this example:
e.g: Work out 23% of 229

Step 1: Divide the percentage by 100: 23/100 = 0.23
Step 2: Multiply this answer with the number to get the final answer: 0.23 x 229 = 52.67

To work out one number as a percentage of another:

e.g: 20 out of the 65 people who attended a maths seminar were Healthcare Assistants. What percentage is this?

Answer : (20/65) * 100 = 0.3077 x 100 = 30.77%
