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:

^{6.3} / _{100} = ^{Part} / _{1}

Cross multiply:

6.3 x 1 = 100 x Part, or

6.3 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{6.3} / _{100} = 0.063

Use again the same percentage formula:

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

^{%} / _{100} = ^{6.3} / _{1}

Cross multiply:

% x 1 = 6.3 x 100

Divide by 1 and get the percentage:

% = ^{6.3 x 100} / _{1} = 630%
