395.5 is what percent of 837 - 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 837 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 837, so we can write it down as 100%=837.
4. We know, that x% equals 395.5 of the output value, so we can write it down as x%=395.5.
5. Now we have two simple equations:
1) 100%=837
2) x%=395.5
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%=837/395.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 395.5 is what percent of 837

100%/x%=837/395.5
(100/x)*x=(837/395.5)*x       - we multiply both sides of the equation by x
100=2.1163084702908*x       - we divide both sides of the equation by (2.1163084702908) to get x
100/2.1163084702908=x
47.252090800478=x
x=47.252090800478

now we have:
395.5 is 47.252090800478% of 837
