316.55 is what percent of 388 - 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 388 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 388, so we can write it down as 100%=388.
4. We know, that x% equals 316.55 of the output value, so we can write it down as x%=316.55.
5. Now we have two simple equations:
1) 100%=388
2) x%=316.55
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%=388/316.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 316.55 is what percent of 388

100%/x%=388/316.55
(100/x)*x=(388/316.55)*x       - we multiply both sides of the equation by x
100=1.2257147370084*x       - we divide both sides of the equation by (1.2257147370084) to get x
100/1.2257147370084=x
81.585051546392=x
x=81.585051546392

now we have:
316.55 is 81.585051546392% of 388
