How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 5.4% of 20?

Always use this formula to find a percentage:

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

5.4 / 100 = Part / 20

Cross multiply:

5.4 x 20 = 100 x Part, or

108 = 100 x Part

Now, divide by 100 and get the answer:

Part = 108 / 100 = 1.08

2) 5.4 is what percent of 20?

Use again the same percentage formula:

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

% / 100 = 5.4 / 20

Cross multiply:

% x 20 = 5.4 x 100

Divide by 20 and get the percentage:

% = 5.4 x 100 / 20 = 27%
