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:

^{13} / _{100} = ^{Part} / _{90000}

Cross multiply:

13 x 90000 = 100 x Part, or

1170000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{1170000} / _{100} = 11700

Use again the same percentage formula:

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

^{%} / _{100} = ^{13} / _{90000}

Cross multiply:

% x 90000 = 13 x 100

Divide by 90000 and get the percentage:

% = ^{13 x 100} / _{90000} = 0.014444444444444%
