248.5 is what percent of 350 - 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 350 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 350, so we can write it down as 100%=350.
4. We know, that x% equals 248.5 of the output value, so we can write it down as x%=248.5.
5. Now we have two simple equations:
1) 100%=350
2) x%=248.5
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%=350/248.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 248.5 is what percent of 350

100%/x%=350/248.5
(100/x)*x=(350/248.5)*x       - we multiply both sides of the equation by x
100=1.4084507042254*x       - we divide both sides of the equation by (1.4084507042254) to get x
100/1.4084507042254=x
71=x
x=71

now we have:
248.5 is 71% of 350
