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} / _{4/5}

Cross multiply:

19 x 4/5 = 100 x Part, or

15.2 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{15.2} / _{100} = 0.76

Use again the same percentage formula:

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

^{%} / _{100} = ^{19} / _{4/5}

Cross multiply:

% x 4/5 = 19 x 100

Divide by 4/5 and get the percentage:

% = ^{19 x 100} / _{4/5} = 2375%
