How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 5.8% of 90?

Always use this formula to find a percentage:

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

5.8 / 100 = Part / 90

Cross multiply:

5.8 x 90 = 100 x Part, or

522 = 100 x Part

Now, divide by 100 and get the answer:

Part = 522 / 100 = 5.22

2) 5.8 is what percent of 90?

Use again the same percentage formula:

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

% / 100 = 5.8 / 90

Cross multiply:

% x 90 = 5.8 x 100

Divide by 90 and get the percentage:

% = 5.8 x 100 / 90 = 6.4444444444444%
