How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 2.4% of 31?

Always use this formula to find a percentage:

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

2.4 / 100 = Part / 31

Cross multiply:

2.4 x 31 = 100 x Part, or

74.4 = 100 x Part

Now, divide by 100 and get the answer:

Part = 74.4 / 100 = 0.744

2) 2.4 is what percent of 31?

Use again the same percentage formula:

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

% / 100 = 2.4 / 31

Cross multiply:

% x 31 = 2.4 x 100

Divide by 31 and get the percentage:

% = 2.4 x 100 / 31 = 7.741935483871%
