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:

^{7.8} / _{100} = ^{Part} / _{7}

Cross multiply:

7.8 x 7 = 100 x Part, or

54.6 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{54.6} / _{100} = 0.546

Use again the same percentage formula:

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

^{%} / _{100} = ^{7.8} / _{7}

Cross multiply:

% x 7 = 7.8 x 100

Divide by 7 and get the percentage:

% = ^{7.8 x 100} / _{7} = 111.42857142857%
