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} / _{15}

Cross multiply:

1.7 x 15 = 100 x Part, or

25.5 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{25.5} / _{100} = 0.255

Use again the same percentage formula:

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

^{%} / _{100} = ^{1.7} / _{15}

Cross multiply:

% x 15 = 1.7 x 100

Divide by 15 and get the percentage:

% = ^{1.7 x 100} / _{15} = 11.333333333333%
