68.2 is what percent of 155 - 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 155 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 155, so we can write it down as 100%=155.
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%=155
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%=155/68.2
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 155

100%/x%=155/68.2
(100/x)*x=(155/68.2)*x       - we multiply both sides of the equation by x
100=2.2727272727273*x       - we divide both sides of the equation by (2.2727272727273) to get x
100/2.2727272727273=x
44=x
x=44

now we have:
68.2 is 44% of 155
