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:

^{7.6} / _{100} = ^{Part} / _{40000}

Cross multiply:

7.6 x 40000 = 100 x Part, or

304000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{304000} / _{100} = 3040

Use again the same percentage formula:

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

^{%} / _{100} = ^{7.6} / _{40000}

Cross multiply:

% x 40000 = 7.6 x 100

Divide by 40000 and get the percentage:

% = ^{7.6 x 100} / _{40000} = 0.019%
