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:

^{2.5} / _{100} = ^{Part} / _{3/4}

Cross multiply:

2.5 x 3/4 = 100 x Part, or

1.875 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{1.875} / _{100} = 0.075

Use again the same percentage formula:

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

^{%} / _{100} = ^{2.5} / _{3/4}

Cross multiply:

% x 3/4 = 2.5 x 100

Divide by 3/4 and get the percentage:

% = ^{2.5 x 100} / _{3/4} = 333.33333333333%
