How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 2.6% of 7/10?

Always use this formula to find a percentage:

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

^2.6 / ₁₀₀ = ^Part / _7/10

Cross multiply:

2.6 x 7/10 = 100 x Part, or

1.82 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^1.82 / ₁₀₀ = 0.182

2) 2.6 is what percent of 7/10?

Use again the same percentage formula:

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

^% / ₁₀₀ = ^2.6 / _7/10

Cross multiply:

% x 7/10 = 2.6 x 100

Divide by 7/10 and get the percentage:

% = ^{2.6 x 100} / _7/10 = 371.42857142857%
