261.87 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 261.87 of the output value, so we can write it down as x%=261.87.
5. Now we have two simple equations:
1) 100%=388
2) x%=261.87
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%=388/261.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 261.87 is what percent of 388

100%/x%=388/261.87
(100/x)*x=(388/261.87)*x       - we multiply both sides of the equation by x
100=1.4816512009776*x       - we divide both sides of the equation by (1.4816512009776) to get x
100/1.4816512009776=x
67.492268041237=x
x=67.492268041237

now we have:
261.87 is 67.492268041237% of 388
