See the solutions to these problems just after the percentage calculator below.

Here are the solutions to the questions stated above:

Always use this formula to find a percentage:

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

^{27} / _{100} = ^{Part} / _{20.99}

Cross multiply:

27 x 20.99 = 100 x Part, or

566.73 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{566.73} / _{100} = 5.6673

Use again the same percentage formula:

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

^{%} / _{100} = ^{27} / _{20.99}

Cross multiply:

% x 20.99 = 27 x 100

Divide by 20.99 and get the percentage:

% = ^{27 x 100} / _{20.99} = 128.63268222963%
