229.5 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 229.5 of the output value, so we can write it down as x%=229.5.
5. Now we have two simple equations:
1) 100%=320
2) x%=229.5
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%=320/229.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 229.5 is what percent of 320

100%/x%=320/229.5
(100/x)*x=(320/229.5)*x       - we multiply both sides of the equation by x
100=1.3943355119826*x       - we divide both sides of the equation by (1.3943355119826) to get x
100/1.3943355119826=x
71.71875=x
x=71.71875

now we have:
229.5 is 71.71875% of 320
