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:

^{9} / _{100} = ^{Part} / _{7.99}

Cross multiply:

9 x 7.99 = 100 x Part, or

71.91 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{71.91} / _{100} = 0.7191

Use again the same percentage formula:

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

^{%} / _{100} = ^{9} / _{7.99}

Cross multiply:

% x 7.99 = 9 x 100

Divide by 7.99 and get the percentage:

% = ^{9 x 100} / _{7.99} = 112.64080100125%
