How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 8.7% of 100000?

Always use this formula to find a percentage:

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

8.7 / 100 = Part / 100000

Cross multiply:

8.7 x 100000 = 100 x Part, or

870000 = 100 x Part

Now, divide by 100 and get the answer:

Part = 870000 / 100 = 8700

2) 8.7 is what percent of 100000?

Use again the same percentage formula:

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

% / 100 = 8.7 / 100000

Cross multiply:

% x 100000 = 8.7 x 100

Divide by 100000 and get the percentage:

% = 8.7 x 100 / 100000 = 0.0087%
