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:

^{4.3} / _{100} = ^{Part} / _{500}

Cross multiply:

4.3 x 500 = 100 x Part, or

2150 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{2150} / _{100} = 21.5

Use again the same percentage formula:

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

^{%} / _{100} = ^{4.3} / _{500}

Cross multiply:

% x 500 = 4.3 x 100

Divide by 500 and get the percentage:

% = ^{4.3 x 100} / _{500} = 0.86%
