How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 3.2% of 400?

Always use this formula to find a percentage:

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

3.2 / 100 = Part / 400

Cross multiply:

3.2 x 400 = 100 x Part, or

1280 = 100 x Part

Now, divide by 100 and get the answer:

Part = 1280 / 100 = 12.8

2) 3.2 is what percent of 400?

Use again the same percentage formula:

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

% / 100 = 3.2 / 400

Cross multiply:

% x 400 = 3.2 x 100

Divide by 400 and get the percentage:

% = 3.2 x 100 / 400 = 0.8%
