17 is what percent of 3902 - 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 3902 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 3902, so we can write it down as 100%=3902.
4. We know, that x% equals 17 of the output value, so we can write it down as x%=17.
5. Now we have two simple equations:
1) 100%=3902
2) x%=17
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%=3902/17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17 is what percent of 3902

100%/x%=3902/17
(100/x)*x=(3902/17)*x       - we multiply both sides of the equation by x
100=229.52941176471*x       - we divide both sides of the equation by (229.52941176471) to get x
100/229.52941176471=x
0.4356740133265=x
x=0.4356740133265

now we have:
17 is 0.4356740133265% of 3902
