3938.64 is what percent of 5700 - 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 5700 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 5700, so we can write it down as 100%=5700.
4. We know, that x% equals 3938.64 of the output value, so we can write it down as x%=3938.64.
5. Now we have two simple equations:
1) 100%=5700
2) x%=3938.64
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%=5700/3938.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3938.64 is what percent of 5700

100%/x%=5700/3938.64
(100/x)*x=(5700/3938.64)*x       - we multiply both sides of the equation by x
100=1.4472000487478*x       - we divide both sides of the equation by (1.4472000487478) to get x
100/1.4472000487478=x
69.098947368421=x
x=69.098947368421

now we have:
3938.64 is 69.098947368421% of 5700
