54 is what percent of 5640 - 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 5640 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 5640, so we can write it down as 100%=5640.
4. We know, that x% equals 54 of the output value, so we can write it down as x%=54.
5. Now we have two simple equations:
1) 100%=5640
2) x%=54
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%=5640/54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54 is what percent of 5640

100%/x%=5640/54
(100/x)*x=(5640/54)*x       - we multiply both sides of the equation by x
100=104.44444444444*x       - we divide both sides of the equation by (104.44444444444) to get x
100/104.44444444444=x
0.95744680851064=x
x=0.95744680851064

now we have:
54 is 0.95744680851064% of 5640
