How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 3.1% of 120?

Always use this formula to find a percentage:

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

3.1 / 100 = Part / 120

Cross multiply:

3.1 x 120 = 100 x Part, or

372 = 100 x Part

Now, divide by 100 and get the answer:

Part = 372 / 100 = 3.72

2) 3.1 is what percent of 120?

Use again the same percentage formula:

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

% / 100 = 3.1 / 120

Cross multiply:

% x 120 = 3.1 x 100

Divide by 120 and get the percentage:

% = 3.1 x 100 / 120 = 2.5833333333333%
