64 is what percent of 7500 - 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 7500 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 7500, so we can write it down as 100%=7500.
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%=7500
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%=7500/64
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 7500

100%/x%=7500/64
(100/x)*x=(7500/64)*x       - we multiply both sides of the equation by x
100=117.1875*x       - we divide both sides of the equation by (117.1875) to get x
100/117.1875=x
0.85333333333333=x
x=0.85333333333333

now we have:
64 is 0.85333333333333% of 7500
