64 is what percent of 2199 - 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 2199 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 2199, so we can write it down as 100%=2199.
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%=2199
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%=2199/64
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 2199

100%/x%=2199/64
(100/x)*x=(2199/64)*x       - we multiply both sides of the equation by x
100=34.359375*x       - we divide both sides of the equation by (34.359375) to get x
100/34.359375=x
2.9104138244657=x
x=2.9104138244657

now we have:
64 is 2.9104138244657% of 2199
