7.64 is what percent of 8.71 - 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 8.71 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 8.71, so we can write it down as 100%=8.71.
4. We know, that x% equals 7.64 of the output value, so we can write it down as x%=7.64.
5. Now we have two simple equations:
1) 100%=8.71
2) x%=7.64
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%=8.71/7.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.64 is what percent of 8.71

100%/x%=8.71/7.64
(100/x)*x=(8.71/7.64)*x       - we multiply both sides of the equation by x
100=1.1400523560209*x       - we divide both sides of the equation by (1.1400523560209) to get x
100/1.1400523560209=x
87.715269804822=x
x=87.715269804822

now we have:
7.64 is 87.715269804822% of 8.71
