64.95 is what percent of 850 - 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 850 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 850, so we can write it down as 100%=850.
4. We know, that x% equals 64.95 of the output value, so we can write it down as x%=64.95.
5. Now we have two simple equations:
1) 100%=850
2) x%=64.95
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%=850/64.95
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64.95 is what percent of 850

100%/x%=850/64.95
(100/x)*x=(850/64.95)*x       - we multiply both sides of the equation by x
100=13.086989992302*x       - we divide both sides of the equation by (13.086989992302) to get x
100/13.086989992302=x
7.6411764705882=x
x=7.6411764705882

now we have:
64.95 is 7.6411764705882% of 850
