How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 6.7% of 4/10?

Always use this formula to find a percentage:

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

6.7 / 100 = Part / 4/10

Cross multiply:

6.7 x 4/10 = 100 x Part, or

2.68 = 100 x Part

Now, divide by 100 and get the answer:

Part = 2.68 / 100 = 0.268

2) 6.7 is what percent of 4/10?

Use again the same percentage formula:

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

% / 100 = 6.7 / 4/10

Cross multiply:

% x 4/10 = 6.7 x 100

Divide by 4/10 and get the percentage:

% = 6.7 x 100 / 4/10 = 1675%
