389.2 is what percent of 427.04 - 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 427.04 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 427.04, so we can write it down as 100%=427.04.
4. We know, that x% equals 389.2 of the output value, so we can write it down as x%=389.2.
5. Now we have two simple equations:
1) 100%=427.04
2) x%=389.2
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%=427.04/389.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 389.2 is what percent of 427.04

100%/x%=427.04/389.2
(100/x)*x=(427.04/389.2)*x       - we multiply both sides of the equation by x
100=1.0972250770812*x       - we divide both sides of the equation by (1.0972250770812) to get x
100/1.0972250770812=x
91.139003372049=x
x=91.139003372049

now we have:
389.2 is 91.139003372049% of 427.04
