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:

^{1.3} / _{100} = ^{Part} / _{20}

Cross multiply:

1.3 x 20 = 100 x Part, or

26 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{26} / _{100} = 0.26

Use again the same percentage formula:

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

^{%} / _{100} = ^{1.3} / _{20}

Cross multiply:

% x 20 = 1.3 x 100

Divide by 20 and get the percentage:

% = ^{1.3 x 100} / _{20} = 6.5%
