27.6 is what percent of 555 - 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 555 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 555, so we can write it down as 100%=555.
4. We know, that x% equals 27.6 of the output value, so we can write it down as x%=27.6.
5. Now we have two simple equations:
1) 100%=555
2) x%=27.6
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%=555/27.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.6 is what percent of 555

100%/x%=555/27.6
(100/x)*x=(555/27.6)*x       - we multiply both sides of the equation by x
100=20.108695652174*x       - we divide both sides of the equation by (20.108695652174) to get x
100/20.108695652174=x
4.972972972973=x
x=4.972972972973

now we have:
27.6 is 4.972972972973% of 555
