389.34 is what percent of 1200 - 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 1200 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 1200, so we can write it down as 100%=1200.
4. We know, that x% equals 389.34 of the output value, so we can write it down as x%=389.34.
5. Now we have two simple equations:
1) 100%=1200
2) x%=389.34
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%=1200/389.34
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 389.34 is what percent of 1200

100%/x%=1200/389.34
(100/x)*x=(1200/389.34)*x       - we multiply both sides of the equation by x
100=3.0821390044691*x       - we divide both sides of the equation by (3.0821390044691) to get x
100/3.0821390044691=x
32.445=x
x=32.445

now we have:
389.34 is 32.445% of 1200
