How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 30% of 30000?

Always use this formula to find a percentage:

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

30 / 100 = Part / 30000

Cross multiply:

30 x 30000 = 100 x Part, or

900000 = 100 x Part

Now, divide by 100 and get the answer:

Part = 900000 / 100 = 9000

2) 30 is what percent of 30000?

Use again the same percentage formula:

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

% / 100 = 30 / 30000

Cross multiply:

% x 30000 = 30 x 100

Divide by 30000 and get the percentage:

% = 30 x 100 / 30000 = 0.1%
