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:

^{3.7} / _{100} = ^{Part} / _{10000000}

Cross multiply:

3.7 x 10000000 = 100 x Part, or

37000000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{37000000} / _{100} = 370000

Use again the same percentage formula:

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

^{%} / _{100} = ^{3.7} / _{10000000}

Cross multiply:

% x 10000000 = 3.7 x 100

Divide by 10000000 and get the percentage:

% = ^{3.7 x 100} / _{10000000} = 3.7E-5%
