136.5 is what percent of 216.5 - 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 216.5 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 216.5, so we can write it down as 100%=216.5.
4. We know, that x% equals 136.5 of the output value, so we can write it down as x%=136.5.
5. Now we have two simple equations:
1) 100%=216.5
2) x%=136.5
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%=216.5/136.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 136.5 is what percent of 216.5

100%/x%=216.5/136.5
(100/x)*x=(216.5/136.5)*x       - we multiply both sides of the equation by x
100=1.5860805860806*x       - we divide both sides of the equation by (1.5860805860806) to get x
100/1.5860805860806=x
63.048498845266=x
x=63.048498845266

now we have:
136.5 is 63.048498845266% of 216.5
