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:

^{7.2} / _{100} = ^{Part} / _{10}

Cross multiply:

7.2 x 10 = 100 x Part, or

72 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{72} / _{100} = 0.72

Use again the same percentage formula:

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

^{%} / _{100} = ^{7.2} / _{10}

Cross multiply:

% x 10 = 7.2 x 100

Divide by 10 and get the percentage:

% = ^{7.2 x 100} / _{10} = 72%
