How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 31% of 1/5?

Always use this formula to find a percentage:

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

31 / 100 = Part / 1/5

Cross multiply:

31 x 1/5 = 100 x Part, or

6.2 = 100 x Part

Now, divide by 100 and get the answer:

Part = 6.2 / 100 = 0.31

2) 31 is what percent of 1/5?

Use again the same percentage formula:

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

% / 100 = 31 / 1/5

Cross multiply:

% x 1/5 = 31 x 100

Divide by 1/5 and get the percentage:

% = 31 x 100 / 1/5 = 15500%
