How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 6.9% of 30.99?

Always use this formula to find a percentage:

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

6.9 / 100 = Part / 30.99

Cross multiply:

6.9 x 30.99 = 100 x Part, or

213.831 = 100 x Part

Now, divide by 100 and get the answer:

Part = 213.831 / 100 = 2.13831

2) 6.9 is what percent of 30.99?

Use again the same percentage formula:

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

% / 100 = 6.9 / 30.99

Cross multiply:

% x 30.99 = 6.9 x 100

Divide by 30.99 and get the percentage:

% = 6.9 x 100 / 30.99 = 22.265246853824%
