64.4 is what percent of 495 - 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 495 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 495, so we can write it down as 100%=495.
4. We know, that x% equals 64.4 of the output value, so we can write it down as x%=64.4.
5. Now we have two simple equations:
1) 100%=495
2) x%=64.4
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%=495/64.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64.4 is what percent of 495

100%/x%=495/64.4
(100/x)*x=(495/64.4)*x       - we multiply both sides of the equation by x
100=7.6863354037267*x       - we divide both sides of the equation by (7.6863354037267) to get x
100/7.6863354037267=x
13.010101010101=x
x=13.010101010101

now we have:
64.4 is 13.010101010101% of 495
