1289.23 is what percent of 3680 - 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 3680 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 3680, so we can write it down as 100%=3680.
4. We know, that x% equals 1289.23 of the output value, so we can write it down as x%=1289.23.
5. Now we have two simple equations:
1) 100%=3680
2) x%=1289.23
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%=3680/1289.23
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1289.23 is what percent of 3680

100%/x%=3680/1289.23
(100/x)*x=(3680/1289.23)*x       - we multiply both sides of the equation by x
100=2.8544169775758*x       - we divide both sides of the equation by (2.8544169775758) to get x
100/2.8544169775758=x
35.033423913043=x
x=35.033423913043

now we have:
1289.23 is 35.033423913043% of 3680
