17.6 is what percent of 38.9 - 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 38.9 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 38.9, so we can write it down as 100%=38.9.
4. We know, that x% equals 17.6 of the output value, so we can write it down as x%=17.6.
5. Now we have two simple equations:
1) 100%=38.9
2) x%=17.6
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%=38.9/17.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.6 is what percent of 38.9

100%/x%=38.9/17.6
(100/x)*x=(38.9/17.6)*x       - we multiply both sides of the equation by x
100=2.2102272727273*x       - we divide both sides of the equation by (2.2102272727273) to get x
100/2.2102272727273=x
45.244215938303=x
x=45.244215938303

now we have:
17.6 is 45.244215938303% of 38.9
