55.9 is what percent of 68 - 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 68 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 68, so we can write it down as 100%=68.
4. We know, that x% equals 55.9 of the output value, so we can write it down as x%=55.9.
5. Now we have two simple equations:
1) 100%=68
2) x%=55.9
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%=68/55.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55.9 is what percent of 68

100%/x%=68/55.9
(100/x)*x=(68/55.9)*x       - we multiply both sides of the equation by x
100=1.216457960644*x       - we divide both sides of the equation by (1.216457960644) to get x
100/1.216457960644=x
82.205882352941=x
x=82.205882352941

now we have:
55.9 is 82.205882352941% of 68
