How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 8.7% of 28?

Always use this formula to find a percentage:

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

8.7 / 100 = Part / 28

Cross multiply:

8.7 x 28 = 100 x Part, or

243.6 = 100 x Part

Now, divide by 100 and get the answer:

Part = 243.6 / 100 = 2.436

2) 8.7 is what percent of 28?

Use again the same percentage formula:

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

% / 100 = 8.7 / 28

Cross multiply:

% x 28 = 8.7 x 100

Divide by 28 and get the percentage:

% = 8.7 x 100 / 28 = 31.071428571429%
