89.5 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 89.5 of the output value, so we can write it down as x%=89.5.
5. Now we have two simple equations:
1) 100%=257
2) x%=89.5
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%=257/89.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89.5 is what percent of 257

100%/x%=257/89.5
(100/x)*x=(257/89.5)*x       - we multiply both sides of the equation by x
100=2.8715083798883*x       - we divide both sides of the equation by (2.8715083798883) to get x
100/2.8715083798883=x
34.824902723735=x
x=34.824902723735

now we have:
89.5 is 34.824902723735% of 257
