38.5 is what percent of 55.5 - 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 55.5 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 55.5, so we can write it down as 100%=55.5.
4. We know, that x% equals 38.5 of the output value, so we can write it down as x%=38.5.
5. Now we have two simple equations:
1) 100%=55.5
2) x%=38.5
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%=55.5/38.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.5 is what percent of 55.5

100%/x%=55.5/38.5
(100/x)*x=(55.5/38.5)*x       - we multiply both sides of the equation by x
100=1.4415584415584*x       - we divide both sides of the equation by (1.4415584415584) to get x
100/1.4415584415584=x
69.369369369369=x
x=69.369369369369

now we have:
38.5 is 69.369369369369% of 55.5
