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:

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

Cross multiply:

10 x 9/10 = 100 x Part, or

9 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{9} / _{100} = 0.9

Use again the same percentage formula:

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

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

Cross multiply:

% x 9/10 = 10 x 100

Divide by 9/10 and get the percentage:

% = ^{10 x 100} / _{9/10} = 1111.1111111111%
