## How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

### 1) What is 90% of 1/2?

Always use this formula to find a percentage:

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

^{90} / _{100} = ^{Part} / _{1/2}

Cross multiply:

90 x 1/2 = 100 x Part, or

45 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{45} / _{100} = 0.9

### 2) 90 is what percent of 1/2?

Use again the same percentage formula:

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

^{%} / _{100} = ^{90} / _{1/2}

Cross multiply:

% x 1/2 = 90 x 100

Divide by 1/2 and get the percentage:

% = ^{90 x 100} / _{1/2} = 18000%
