7 is what percent of 56.5 - 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 56.5 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 56.5, so we can write it down as 100%=56.5.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=56.5
2) x%=7
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%=56.5/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 56.5

100%/x%=56.5/7
(100/x)*x=(56.5/7)*x       - we multiply both sides of the equation by x
100=8.0714285714286*x       - we divide both sides of the equation by (8.0714285714286) to get x
100/8.0714285714286=x
12.389380530973=x
x=12.389380530973

now we have:
7 is 12.389380530973% of 56.5
