33.93 is what percent of 638 - 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 638 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 638, so we can write it down as 100%=638.
4. We know, that x% equals 33.93 of the output value, so we can write it down as x%=33.93.
5. Now we have two simple equations:
1) 100%=638
2) x%=33.93
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%=638/33.93
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 33.93 is what percent of 638

100%/x%=638/33.93
(100/x)*x=(638/33.93)*x       - we multiply both sides of the equation by x
100=18.803418803419*x       - we divide both sides of the equation by (18.803418803419) to get x
100/18.803418803419=x
5.3181818181818=x
x=5.3181818181818

now we have:
33.93 is 5.3181818181818% of 638
