How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 2.8% of 100.99?

Always use this formula to find a percentage:

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

2.8 / 100 = Part / 100.99

Cross multiply:

2.8 x 100.99 = 100 x Part, or

282.772 = 100 x Part

Now, divide by 100 and get the answer:

Part = 282.772 / 100 = 2.82772

2) 2.8 is what percent of 100.99?

Use again the same percentage formula:

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

% / 100 = 2.8 / 100.99

Cross multiply:

% x 100.99 = 2.8 x 100

Divide by 100.99 and get the percentage:

% = 2.8 x 100 / 100.99 = 2.7725517377958%
