173.5 is what percent of 421.5 - 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 421.5 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 421.5, so we can write it down as 100%=421.5.
4. We know, that x% equals 173.5 of the output value, so we can write it down as x%=173.5.
5. Now we have two simple equations:
1) 100%=421.5
2) x%=173.5
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%=421.5/173.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 173.5 is what percent of 421.5

100%/x%=421.5/173.5
(100/x)*x=(421.5/173.5)*x       - we multiply both sides of the equation by x
100=2.4293948126801*x       - we divide both sides of the equation by (2.4293948126801) to get x
100/2.4293948126801=x
41.162514827995=x
x=41.162514827995

now we have:
173.5 is 41.162514827995% of 421.5
