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:

^{11} / _{100} = ^{Part} / _{180}

Cross multiply:

11 x 180 = 100 x Part, or

1980 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{1980} / _{100} = 19.8

Use again the same percentage formula:

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

^{%} / _{100} = ^{11} / _{180}

Cross multiply:

% x 180 = 11 x 100

Divide by 180 and get the percentage:

% = ^{11 x 100} / _{180} = 6.1111111111111%
