19.56 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 19.56 of the output value, so we can write it down as x%=19.56.
5. Now we have two simple equations:
1) 100%=320
2) x%=19.56
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%=320/19.56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.56 is what percent of 320

100%/x%=320/19.56
(100/x)*x=(320/19.56)*x       - we multiply both sides of the equation by x
100=16.359918200409*x       - we divide both sides of the equation by (16.359918200409) to get x
100/16.359918200409=x
6.1125=x
x=6.1125

now we have:
19.56 is 6.1125% of 320
