74.5 is what percent of 187 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 187 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 187, so we can write it down as 100%=187.
4. We know, that x% equals 74.5 of the output value, so we can write it down as x%=74.5.
5. Now we have two simple equations:
1) 100%=187
2) x%=74.5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=187/74.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74.5 is what percent of 187

100%/x%=187/74.5
(100/x)*x=(187/74.5)*x       - we multiply both sides of the equation by x
100=2.510067114094*x       - we divide both sides of the equation by (2.510067114094) to get x
100/2.510067114094=x
39.839572192513=x
x=39.839572192513

now we have:
74.5 is 39.839572192513% of 187
