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:

^{3.2} / _{100} = ^{Part} / _{45000}

Cross multiply:

3.2 x 45000 = 100 x Part, or

144000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{144000} / _{100} = 1440

Use again the same percentage formula:

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

^{%} / _{100} = ^{3.2} / _{45000}

Cross multiply:

% x 45000 = 3.2 x 100

Divide by 45000 and get the percentage:

% = ^{3.2 x 100} / _{45000} = 0.0071111111111111%
