389.31 is what percent of 810.69 - 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 810.69 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 810.69, so we can write it down as 100%=810.69.
4. We know, that x% equals 389.31 of the output value, so we can write it down as x%=389.31.
5. Now we have two simple equations:
1) 100%=810.69
2) x%=389.31
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%=810.69/389.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 389.31 is what percent of 810.69

100%/x%=810.69/389.31
(100/x)*x=(810.69/389.31)*x       - we multiply both sides of the equation by x
100=2.082376512291*x       - we divide both sides of the equation by (2.082376512291) to get x
100/2.082376512291=x
48.022055286238=x
x=48.022055286238

now we have:
389.31 is 48.022055286238% of 810.69
