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:

^{1.5} / _{100} = ^{Part} / _{4/5}

Cross multiply:

1.5 x 4/5 = 100 x Part, or

1.2 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{1.2} / _{100} = 0.06

Use again the same percentage formula:

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

^{%} / _{100} = ^{1.5} / _{4/5}

Cross multiply:

% x 4/5 = 1.5 x 100

Divide by 4/5 and get the percentage:

% = ^{1.5 x 100} / _{4/5} = 187.5%
