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:

^{80} / _{100} = ^{Part} / _{100000}

Cross multiply:

80 x 100000 = 100 x Part, or

8000000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{8000000} / _{100} = 80000

Use again the same percentage formula:

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

^{%} / _{100} = ^{80} / _{100000}

Cross multiply:

% x 100000 = 80 x 100

Divide by 100000 and get the percentage:

% = ^{80 x 100} / _{100000} = 0.08%
