38.1 is what percent of 85 - 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 85 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 85, so we can write it down as 100%=85.
4. We know, that x% equals 38.1 of the output value, so we can write it down as x%=38.1.
5. Now we have two simple equations:
1) 100%=85
2) x%=38.1
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%=85/38.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.1 is what percent of 85

100%/x%=85/38.1
(100/x)*x=(85/38.1)*x       - we multiply both sides of the equation by x
100=2.2309711286089*x       - we divide both sides of the equation by (2.2309711286089) to get x
100/2.2309711286089=x
44.823529411765=x
x=44.823529411765

now we have:
38.1 is 44.823529411765% of 85
