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} / _{4000000}

Cross multiply:

27 x 4000000 = 100 x Part, or

108000000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{108000000} / _{100} = 1080000

Use again the same percentage formula:

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

^{%} / _{100} = ^{27} / _{4000000}

Cross multiply:

% x 4000000 = 27 x 100

Divide by 4000000 and get the percentage:

% = ^{27 x 100} / _{4000000} = 0.000675%
