34.92 is what percent of 38.8 - 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 38.8 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 38.8, so we can write it down as 100%=38.8.
4. We know, that x% equals 34.92 of the output value, so we can write it down as x%=34.92.
5. Now we have two simple equations:
1) 100%=38.8
2) x%=34.92
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%=38.8/34.92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 34.92 is what percent of 38.8

100%/x%=38.8/34.92
(100/x)*x=(38.8/34.92)*x       - we multiply both sides of the equation by x
100=1.1111111111111*x       - we divide both sides of the equation by (1.1111111111111) to get x
100/1.1111111111111=x
90=x
x=90

now we have:
34.92 is 90% of 38.8
