How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 55% of 30.99?

Always use this formula to find a percentage:

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

55 / 100 = Part / 30.99

Cross multiply:

55 x 30.99 = 100 x Part, or

1704.45 = 100 x Part

Now, divide by 100 and get the answer:

Part = 1704.45 / 100 = 17.0445

2) 55 is what percent of 30.99?

Use again the same percentage formula:

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

% / 100 = 55 / 30.99

Cross multiply:

% x 30.99 = 55 x 100

Divide by 30.99 and get the percentage:

% = 55 x 100 / 30.99 = 177.47660535657%
