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:

^{8.5} / _{100} = ^{Part} / _{17}

Cross multiply:

8.5 x 17 = 100 x Part, or

144.5 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{144.5} / _{100} = 1.445

Use again the same percentage formula:

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

^{%} / _{100} = ^{8.5} / _{17}

Cross multiply:

% x 17 = 8.5 x 100

Divide by 17 and get the percentage:

% = ^{8.5 x 100} / _{17} = 50%
