How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 2% of 200?

Always use this formula to find a percentage:

^% / ₁₀₀ = ^Part / _Whole replace the given values:

² / ₁₀₀ = ^Part / ₂₀₀

Cross multiply:

2 x 200 = 100 x Part, or

400 = 100 x Part

Now, divide by 100 and get the answer:

Part = ⁴⁰⁰ / ₁₀₀ = 4

2) 2 is what percent of 200?

Use again the same percentage formula:

^% / ₁₀₀ = ^Part / _Whole replace the given values:

^% / ₁₀₀ = ² / ₂₀₀

Cross multiply:

% x 200 = 2 x 100

Divide by 200 and get the percentage:

% = ^{2 x 100} / ₂₀₀ = 1%
