169.5 is what percent of 397.6 - 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 397.6 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 397.6, so we can write it down as 100%=397.6.
4. We know, that x% equals 169.5 of the output value, so we can write it down as x%=169.5.
5. Now we have two simple equations:
1) 100%=397.6
2) x%=169.5
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%=397.6/169.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 169.5 is what percent of 397.6

100%/x%=397.6/169.5
(100/x)*x=(397.6/169.5)*x       - we multiply both sides of the equation by x
100=2.3457227138643*x       - we divide both sides of the equation by (2.3457227138643) to get x
100/2.3457227138643=x
42.630784708249=x
x=42.630784708249

now we have:
169.5 is 42.630784708249% of 397.6
