How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 10% of 21.99?

Always use this formula to find a percentage:

% / 100 = Part / Whole replace the given values:

10 / 100 = Part / 21.99

Cross multiply:

10 x 21.99 = 100 x Part, or

219.9 = 100 x Part

Now, divide by 100 and get the answer:

Part = 219.9 / 100 = 2.199

2) 10 is what percent of 21.99?

Use again the same percentage formula:

% / 100 = Part / Whole replace the given values:

% / 100 = 10 / 21.99

Cross multiply:

% x 21.99 = 10 x 100

Divide by 21.99 and get the percentage:

% = 10 x 100 / 21.99 = 45.475216007276%
