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:

^{5.1} / _{100} = ^{Part} / _{16.99}

Cross multiply:

5.1 x 16.99 = 100 x Part, or

86.649 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{86.649} / _{100} = 0.86649

Use again the same percentage formula:

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

^{%} / _{100} = ^{5.1} / _{16.99}

Cross multiply:

% x 16.99 = 5.1 x 100

Divide by 16.99 and get the percentage:

% = ^{5.1 x 100} / _{16.99} = 30.017657445556%
