39.4 is what percent of 560 - 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 560 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 560, so we can write it down as 100%=560.
4. We know, that x% equals 39.4 of the output value, so we can write it down as x%=39.4.
5. Now we have two simple equations:
1) 100%=560
2) x%=39.4
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%=560/39.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.4 is what percent of 560

100%/x%=560/39.4
(100/x)*x=(560/39.4)*x       - we multiply both sides of the equation by x
100=14.213197969543*x       - we divide both sides of the equation by (14.213197969543) to get x
100/14.213197969543=x
7.0357142857143=x
x=7.0357142857143

now we have:
39.4 is 7.0357142857143% of 560
