387.21 is what percent of 956.91 - 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 956.91 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 956.91, so we can write it down as 100%=956.91.
4. We know, that x% equals 387.21 of the output value, so we can write it down as x%=387.21.
5. Now we have two simple equations:
1) 100%=956.91
2) x%=387.21
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%=956.91/387.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 387.21 is what percent of 956.91

100%/x%=956.91/387.21
(100/x)*x=(956.91/387.21)*x       - we multiply both sides of the equation by x
100=2.471294646316*x       - we divide both sides of the equation by (2.471294646316) to get x
100/2.471294646316=x
40.464620497225=x
x=40.464620497225

now we have:
