250.88 is what percent of 420 - 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 420 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 420, so we can write it down as 100%=420.
4. We know, that x% equals 250.88 of the output value, so we can write it down as x%=250.88.
5. Now we have two simple equations:
1) 100%=420
2) x%=250.88
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%=420/250.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 250.88 is what percent of 420

100%/x%=420/250.88
(100/x)*x=(420/250.88)*x       - we multiply both sides of the equation by x
100=1.6741071428571*x       - we divide both sides of the equation by (1.6741071428571) to get x
100/1.6741071428571=x
59.733333333333=x
x=59.733333333333

now we have:
250.88 is 59.733333333333% of 420
