17.1 is what percent of 39.1 - 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 39.1 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 39.1, so we can write it down as 100%=39.1.
4. We know, that x% equals 17.1 of the output value, so we can write it down as x%=17.1.
5. Now we have two simple equations:
1) 100%=39.1
2) x%=17.1
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%=39.1/17.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.1 is what percent of 39.1

100%/x%=39.1/17.1
(100/x)*x=(39.1/17.1)*x       - we multiply both sides of the equation by x
100=2.2865497076023*x       - we divide both sides of the equation by (2.2865497076023) to get x
100/2.2865497076023=x
43.734015345269=x
x=43.734015345269

now we have:
17.1 is 43.734015345269% of 39.1
