17.92 is what percent of 320 - 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 320 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 320, so we can write it down as 100%=320.
4. We know, that x% equals 17.92 of the output value, so we can write it down as x%=17.92.
5. Now we have two simple equations:
1) 100%=320
2) x%=17.92
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%=320/17.92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.92 is what percent of 320

100%/x%=320/17.92
(100/x)*x=(320/17.92)*x       - we multiply both sides of the equation by x
100=17.857142857143*x       - we divide both sides of the equation by (17.857142857143) to get x
100/17.857142857143=x
5.6=x
x=5.6

now we have:
17.92 is 5.6% of 320
