408.51 is what percent of 459 - 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 459 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 459, so we can write it down as 100%=459.
4. We know, that x% equals 408.51 of the output value, so we can write it down as x%=408.51.
5. Now we have two simple equations:
1) 100%=459
2) x%=408.51
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%=459/408.51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 408.51 is what percent of 459

100%/x%=459/408.51
(100/x)*x=(459/408.51)*x       - we multiply both sides of the equation by x
100=1.123595505618*x       - we divide both sides of the equation by (1.123595505618) to get x
100/1.123595505618=x
89=x
x=89

now we have:
408.51 is 89% of 459
