68.2 is what percent of 55 - 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 55 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 55, so we can write it down as 100%=55.
4. We know, that x% equals 68.2 of the output value, so we can write it down as x%=68.2.
5. Now we have two simple equations:
1) 100%=55
2) x%=68.2
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%=55/68.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 68.2 is what percent of 55

100%/x%=55/68.2
(100/x)*x=(55/68.2)*x       - we multiply both sides of the equation by x
100=0.80645161290323*x       - we divide both sides of the equation by (0.80645161290323) to get x
100/0.80645161290323=x
124=x
x=124

now we have:
68.2 is 124% of 55
