How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 2.3% of 3/5?

Always use this formula to find a percentage:

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

2.3 / 100 = Part / 3/5

Cross multiply:

2.3 x 3/5 = 100 x Part, or

1.38 = 100 x Part

Now, divide by 100 and get the answer:

Part = 1.38 / 100 = 0.069

2) 2.3 is what percent of 3/5?

Use again the same percentage formula:

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

% / 100 = 2.3 / 3/5

Cross multiply:

% x 3/5 = 2.3 x 100

Divide by 3/5 and get the percentage:

% = 2.3 x 100 / 3/5 = 383.33333333333%
