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:

^{15} / _{100} = ^{Part} / _{600000}

Cross multiply:

15 x 600000 = 100 x Part, or

9000000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{9000000} / _{100} = 90000

Use again the same percentage formula:

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

^{%} / _{100} = ^{15} / _{600000}

Cross multiply:

% x 600000 = 15 x 100

Divide by 600000 and get the percentage:

% = ^{15 x 100} / _{600000} = 0.0025%
