171.02 is what percent of 1920 - 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 1920 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 1920, so we can write it down as 100%=1920.
4. We know, that x% equals 171.02 of the output value, so we can write it down as x%=171.02.
5. Now we have two simple equations:
1) 100%=1920
2) x%=171.02
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%=1920/171.02
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 171.02 is what percent of 1920

100%/x%=1920/171.02
(100/x)*x=(1920/171.02)*x       - we multiply both sides of the equation by x
100=11.226757104432*x       - we divide both sides of the equation by (11.226757104432) to get x
100/11.226757104432=x
8.9072916666667=x
x=8.9072916666667

now we have:
171.02 is 8.9072916666667% of 1920
