636.09 is what percent of 745 - 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 745 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 745, so we can write it down as 100%=745.
4. We know, that x% equals 636.09 of the output value, so we can write it down as x%=636.09.
5. Now we have two simple equations:
1) 100%=745
2) x%=636.09
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%=745/636.09
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 636.09 is what percent of 745

100%/x%=745/636.09
(100/x)*x=(745/636.09)*x       - we multiply both sides of the equation by x
100=1.1712179094153*x       - we divide both sides of the equation by (1.1712179094153) to get x
100/1.1712179094153=x
85.381208053691=x
x=85.381208053691

now we have:
636.09 is 85.381208053691% of 745
