How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 30% of 4?

Always use this formula to find a percentage:

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

30 / 100 = Part / 4

Cross multiply:

30 x 4 = 100 x Part, or

120 = 100 x Part

Now, divide by 100 and get the answer:

Part = 120 / 100 = 1.2

2) 30 is what percent of 4?

Use again the same percentage formula:

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

% / 100 = 30 / 4

Cross multiply:

% x 4 = 30 x 100

Divide by 4 and get the percentage:

% = 30 x 100 / 4 = 750%
