185.5 is what percent of 420 - 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 420 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 420, so we can write it down as 100%=420.
4. We know, that x% equals 185.5 of the output value, so we can write it down as x%=185.5.
5. Now we have two simple equations:
1) 100%=420
2) x%=185.5
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%=420/185.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 185.5 is what percent of 420

100%/x%=420/185.5
(100/x)*x=(420/185.5)*x       - we multiply both sides of the equation by x
100=2.2641509433962*x       - we divide both sides of the equation by (2.2641509433962) to get x
100/2.2641509433962=x
44.166666666667=x
x=44.166666666667

now we have:
185.5 is 44.166666666667% of 420
