How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 7.8% of 7?

Always use this formula to find a percentage:

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

7.8 / 100 = Part / 7

Cross multiply:

7.8 x 7 = 100 x Part, or

54.6 = 100 x Part

Now, divide by 100 and get the answer:

Part = 54.6 / 100 = 0.546

2) 7.8 is what percent of 7?

Use again the same percentage formula:

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

% / 100 = 7.8 / 7

Cross multiply:

% x 7 = 7.8 x 100

Divide by 7 and get the percentage:

% = 7.8 x 100 / 7 = 111.42857142857%
