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:

^{16} / _{100} = ^{Part} / _{30.99}

Cross multiply:

16 x 30.99 = 100 x Part, or

495.84 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{495.84} / _{100} = 4.9584

Use again the same percentage formula:

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

^{%} / _{100} = ^{16} / _{30.99}

Cross multiply:

% x 30.99 = 16 x 100

Divide by 30.99 and get the percentage:

% = ^{16 x 100} / _{30.99} = 51.62955792191%
