How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 2.5% of 16?

Always use this formula to find a percentage:

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

2.5 / 100 = Part / 16

Cross multiply:

2.5 x 16 = 100 x Part, or

40 = 100 x Part

Now, divide by 100 and get the answer:

Part = 40 / 100 = 0.4

2) 2.5 is what percent of 16?

Use again the same percentage formula:

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

% / 100 = 2.5 / 16

Cross multiply:

% x 16 = 2.5 x 100

Divide by 16 and get the percentage:

% = 2.5 x 100 / 16 = 15.625%
