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:

^{55} / _{100} = ^{Part} / _{1800}

Cross multiply:

55 x 1800 = 100 x Part, or

99000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{99000} / _{100} = 990

Use again the same percentage formula:

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

^{%} / _{100} = ^{55} / _{1800}

Cross multiply:

% x 1800 = 55 x 100

Divide by 1800 and get the percentage:

% = ^{55 x 100} / _{1800} = 3.0555555555556%
