38 is what percent of 220.5 - 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 220.5 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 220.5, so we can write it down as 100%=220.5.
4. We know, that x% equals 38 of the output value, so we can write it down as x%=38.
5. Now we have two simple equations:
1) 100%=220.5
2) x%=38
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%=220.5/38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38 is what percent of 220.5

100%/x%=220.5/38
(100/x)*x=(220.5/38)*x       - we multiply both sides of the equation by x
100=5.8026315789474*x       - we divide both sides of the equation by (5.8026315789474) to get x
100/5.8026315789474=x
17.233560090703=x
x=17.233560090703

now we have:
38 is 17.233560090703% of 220.5
