86.4 is what percent of 92 - 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 92 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 92, so we can write it down as 100%=92.
4. We know, that x% equals 86.4 of the output value, so we can write it down as x%=86.4.
5. Now we have two simple equations:
1) 100%=92
2) x%=86.4
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%=92/86.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 86.4 is what percent of 92

100%/x%=92/86.4
(100/x)*x=(92/86.4)*x       - we multiply both sides of the equation by x
100=1.0648148148148*x       - we divide both sides of the equation by (1.0648148148148) to get x
100/1.0648148148148=x
93.913043478261=x
x=93.913043478261

now we have:
86.4 is 93.913043478261% of 92
