55 is what percent of 107 - 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 107 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 107, so we can write it down as 100%=107.
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%=107
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%=107/55
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 107

100%/x%=107/55
(100/x)*x=(107/55)*x       - we multiply both sides of the equation by x
100=1.9454545454545*x       - we divide both sides of the equation by (1.9454545454545) to get x
100/1.9454545454545=x
51.401869158879=x
x=51.401869158879

now we have:
55 is 51.401869158879% of 107
