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:

^{7.1} / _{100} = ^{Part} / _{5}

Cross multiply:

7.1 x 5 = 100 x Part, or

35.5 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{35.5} / _{100} = 0.355

Use again the same percentage formula:

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

^{%} / _{100} = ^{7.1} / _{5}

Cross multiply:

% x 5 = 7.1 x 100

Divide by 5 and get the percentage:

% = ^{7.1 x 100} / _{5} = 142%
