87 is what percent of 334 - 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 334 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 334, so we can write it down as 100%=334.
4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.
5. Now we have two simple equations:
1) 100%=334
2) x%=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%=334/87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 334

100%/x%=334/87
(100/x)*x=(334/87)*x       - we multiply both sides of the equation by x
100=3.8390804597701*x       - we divide both sides of the equation by (3.8390804597701) to get x
100/3.8390804597701=x
26.047904191617=x
x=26.047904191617

now we have:
87 is 26.047904191617% of 334
