How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 15% of 31?

Always use this formula to find a percentage:

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

15 / 100 = Part / 31

Cross multiply:

15 x 31 = 100 x Part, or

465 = 100 x Part

Now, divide by 100 and get the answer:

Part = 465 / 100 = 4.65

2) 15 is what percent of 31?

Use again the same percentage formula:

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

% / 100 = 15 / 31

Cross multiply:

% x 31 = 15 x 100

Divide by 31 and get the percentage:

% = 15 x 100 / 31 = 48.387096774194%
