## How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

### 1) What is 5.1% of 1/2?

Always use this formula to find a percentage:

^{%} / _{100} = ^{Part} / _{Whole} replace the given values:

^{5.1} / _{100} = ^{Part} / _{1/2}

Cross multiply:

5.1 x 1/2 = 100 x Part, or

2.55 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{2.55} / _{100} = 0.051

### 2) 5.1 is what percent of 1/2?

Use again the same percentage formula:

^{%} / _{100} = ^{Part} / _{Whole} replace the given values:

^{%} / _{100} = ^{5.1} / _{1/2}

Cross multiply:

% x 1/2 = 5.1 x 100

Divide by 1/2 and get the percentage:

% = ^{5.1 x 100} / _{1/2} = 1020%
