64 is what percent of 455 - 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 455 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 455, so we can write it down as 100%=455.
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%=455
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%=455/64
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 455

100%/x%=455/64
(100/x)*x=(455/64)*x       - we multiply both sides of the equation by x
100=7.109375*x       - we divide both sides of the equation by (7.109375) to get x
100/7.109375=x
14.065934065934=x
x=14.065934065934

now we have:
64 is 14.065934065934% of 455
