55.8 is what percent of 450 - 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 450 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 450, so we can write it down as 100%=450.
4. We know, that x% equals 55.8 of the output value, so we can write it down as x%=55.8.
5. Now we have two simple equations:
1) 100%=450
2) x%=55.8
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%=450/55.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55.8 is what percent of 450

100%/x%=450/55.8
(100/x)*x=(450/55.8)*x       - we multiply both sides of the equation by x
100=8.0645161290323*x       - we divide both sides of the equation by (8.0645161290323) to get x
100/8.0645161290323=x
12.4=x
x=12.4

now we have:
55.8 is 12.4% of 450
