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:

^{1.7} / _{100} = ^{Part} / _{12}

Cross multiply:

1.7 x 12 = 100 x Part, or

20.4 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{20.4} / _{100} = 0.204

Use again the same percentage formula:

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

^{%} / _{100} = ^{1.7} / _{12}

Cross multiply:

% x 12 = 1.7 x 100

Divide by 12 and get the percentage:

% = ^{1.7 x 100} / _{12} = 14.166666666667%
