228.19 is what percent of 320.19 - 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 320.19 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 320.19, so we can write it down as 100%=320.19.
4. We know, that x% equals 228.19 of the output value, so we can write it down as x%=228.19.
5. Now we have two simple equations:
1) 100%=320.19
2) x%=228.19
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%=320.19/228.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 228.19 is what percent of 320.19

100%/x%=320.19/228.19
(100/x)*x=(320.19/228.19)*x       - we multiply both sides of the equation by x
100=1.403172794601*x       - we divide both sides of the equation by (1.403172794601) to get x
100/1.403172794601=x
71.267060183016=x
x=71.267060183016

now we have:
228.19 is 71.267060183016% of 320.19
