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:

^{13} / _{100} = ^{Part} / _{4.99}

Cross multiply:

13 x 4.99 = 100 x Part, or

64.87 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{64.87} / _{100} = 0.6487

Use again the same percentage formula:

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

^{%} / _{100} = ^{13} / _{4.99}

Cross multiply:

% x 4.99 = 13 x 100

Divide by 4.99 and get the percentage:

% = ^{13 x 100} / _{4.99} = 260.52104208417%
