## How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

### 1) What is 100% of 1/5?

Always use this formula to find a percentage:

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

^{100} / _{100} = ^{Part} / _{1/5}

Cross multiply:

100 x 1/5 = 100 x Part, or

20 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{20} / _{100} = 1

### 2) 100 is what percent of 1/5?

^{%} / _{100} = ^{100} / _{1/5}

Cross multiply:

% x 1/5 = 100 x 100

Divide by 1/5 and get the percentage:

% = ^{100 x 100} / _{1/5} = 50000%
