418.91 is what percent of 257 - 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 257 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 257, so we can write it down as 100%=257.
4. We know, that x% equals 418.91 of the output value, so we can write it down as x%=418.91.
5. Now we have two simple equations:
1) 100%=257
2) x%=418.91
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%=257/418.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 418.91 is what percent of 257

100%/x%=257/418.91
(100/x)*x=(257/418.91)*x       - we multiply both sides of the equation by x
100=0.61349693251534*x       - we divide both sides of the equation by (0.61349693251534) to get x
100/0.61349693251534=x
163=x
x=163

now we have:
418.91 is 163% of 257
