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:

^{75} / _{100} = ^{Part} / _{8/9}

Cross multiply:

75 x 8/9 = 100 x Part, or

66.666666666667 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{66.666666666667} / _{100} = 6

Use again the same percentage formula:

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

^{%} / _{100} = ^{75} / _{8/9}

Cross multiply:

% x 8/9 = 75 x 100

Divide by 8/9 and get the percentage:

% = ^{75 x 100} / _{8/9} = 8437.5%
