How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 5.5% of 90000000?

Always use this formula to find a percentage:

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

5.5 / 100 = Part / 90000000

Cross multiply:

5.5 x 90000000 = 100 x Part, or

495000000 = 100 x Part

Now, divide by 100 and get the answer:

Part = 495000000 / 100 = 4950000

2) 5.5 is what percent of 90000000?

Use again the same percentage formula:

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

% / 100 = 5.5 / 90000000

Cross multiply:

% x 90000000 = 5.5 x 100

Divide by 90000000 and get the percentage:

% = 5.5 x 100 / 90000000 = 6.1111111111111E-6%
