64 is what percent of 108 - 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 108 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 108, so we can write it down as 100%=108.
4. We know, that x% equals 64 of the output value, so we can write it down as x%=64.
5. Now we have two simple equations:
1) 100%=108
2) x%=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%=108/64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64 is what percent of 108

100%/x%=108/64
(100/x)*x=(108/64)*x       - we multiply both sides of the equation by x
100=1.6875*x       - we divide both sides of the equation by (1.6875) to get x
100/1.6875=x
59.259259259259=x
x=59.259259259259

now we have:
64 is 59.259259259259% of 108
