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:

^{5} / _{100} = ^{Part} / _{900}

Cross multiply:

5 x 900 = 100 x Part, or

4500 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{4500} / _{100} = 45

Use again the same percentage formula:

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

^{%} / _{100} = ^{5} / _{900}

Cross multiply:

% x 900 = 5 x 100

Divide by 900 and get the percentage:

% = ^{5 x 100} / _{900} = 0.55555555555556%
