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:

^{12} / _{100} = ^{Part} / _{9/10}

Cross multiply:

12 x 9/10 = 100 x Part, or

10.8 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{10.8} / _{100} = 1.08

Use again the same percentage formula:

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

^{%} / _{100} = ^{12} / _{9/10}

Cross multiply:

% x 9/10 = 12 x 100

Divide by 9/10 and get the percentage:

% = ^{12 x 100} / _{9/10} = 1333.3333333333%
