631.8 is what percent of 162 - 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 162 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 162, so we can write it down as 100%=162.
4. We know, that x% equals 631.8 of the output value, so we can write it down as x%=631.8.
5. Now we have two simple equations:
1) 100%=162
2) x%=631.8
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%=162/631.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 631.8 is what percent of 162

100%/x%=162/631.8
(100/x)*x=(162/631.8)*x       - we multiply both sides of the equation by x
100=0.25641025641026*x       - we divide both sides of the equation by (0.25641025641026) to get x
100/0.25641025641026=x
390=x
x=390

now we have:
631.8 is 390% of 162
