55 is what percent of 5181 - 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 5181 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 5181, so we can write it down as 100%=5181.
4. We know, that x% equals 55 of the output value, so we can write it down as x%=55.
5. Now we have two simple equations:
1) 100%=5181
2) x%=55
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%=5181/55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55 is what percent of 5181

100%/x%=5181/55
(100/x)*x=(5181/55)*x       - we multiply both sides of the equation by x
100=94.2*x       - we divide both sides of the equation by (94.2) to get x
100/94.2=x
1.0615711252654=x
x=1.0615711252654

now we have:
55 is 1.0615711252654% of 5181
