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:

^{6} / _{100} = ^{Part} / _{40}

Cross multiply:

6 x 40 = 100 x Part, or

240 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{240} / _{100} = 2.4

Use again the same percentage formula:

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

^{%} / _{100} = ^{6} / _{40}

Cross multiply:

% x 40 = 6 x 100

Divide by 40 and get the percentage:

% = ^{6 x 100} / _{40} = 15%
