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:

^{4} / _{100} = ^{Part} / _{4/10}

Cross multiply:

4 x 4/10 = 100 x Part, or

1.6 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{1.6} / _{100} = 0.16

Use again the same percentage formula:

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

^{%} / _{100} = ^{4} / _{4/10}

Cross multiply:

% x 4/10 = 4 x 100

Divide by 4/10 and get the percentage:

% = ^{4 x 100} / _{4/10} = 1000%
