How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 1.3% of 3.99?

Always use this formula to find a percentage:

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

1.3 / 100 = Part / 3.99

Cross multiply:

1.3 x 3.99 = 100 x Part, or

5.187 = 100 x Part

Now, divide by 100 and get the answer:

Part = 5.187 / 100 = 0.05187

2) 1.3 is what percent of 3.99?

Use again the same percentage formula:

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

% / 100 = 1.3 / 3.99

Cross multiply:

% x 3.99 = 1.3 x 100

Divide by 3.99 and get the percentage:

% = 1.3 x 100 / 3.99 = 32.581453634085%
