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:

^{19} / _{100} = ^{Part} / _{28}

Cross multiply:

19 x 28 = 100 x Part, or

532 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{532} / _{100} = 5.32

Use again the same percentage formula:

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

^{%} / _{100} = ^{19} / _{28}

Cross multiply:

% x 28 = 19 x 100

Divide by 28 and get the percentage:

% = ^{19 x 100} / _{28} = 67.857142857143%
