55.1 is what percent of 220 - 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 220 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 220, so we can write it down as 100%=220.
4. We know, that x% equals 55.1 of the output value, so we can write it down as x%=55.1.
5. Now we have two simple equations:
1) 100%=220
2) x%=55.1
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%=220/55.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55.1 is what percent of 220

100%/x%=220/55.1
(100/x)*x=(220/55.1)*x       - we multiply both sides of the equation by x
100=3.9927404718693*x       - we divide both sides of the equation by (3.9927404718693) to get x
100/3.9927404718693=x
25.045454545455=x
x=25.045454545455

now we have:
55.1 is 25.045454545455% of 220
