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:

^{100} / _{100} = ^{Part} / _{10.99}

Cross multiply:

100 x 10.99 = 100 x Part, or

1099 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{1099} / _{100} = 10.99

Use again the same percentage formula:

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

^{%} / _{100} = ^{100} / _{10.99}

Cross multiply:

% x 10.99 = 100 x 100

Divide by 10.99 and get the percentage:

% = ^{100 x 100} / _{10.99} = 909.91810737034%
