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:

^{5.7} / _{100} = ^{Part} / _{8000}

Cross multiply:

5.7 x 8000 = 100 x Part, or

45600 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{45600} / _{100} = 456

Use again the same percentage formula:

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

^{%} / _{100} = ^{5.7} / _{8000}

Cross multiply:

% x 8000 = 5.7 x 100

Divide by 8000 and get the percentage:

% = ^{5.7 x 100} / _{8000} = 0.07125%
