11.5 is what percent of 258 - 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 258 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 258, so we can write it down as 100%=258.
4. We know, that x% equals 11.5 of the output value, so we can write it down as x%=11.5.
5. Now we have two simple equations:
1) 100%=258
2) x%=11.5
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%=258/11.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.5 is what percent of 258

100%/x%=258/11.5
(100/x)*x=(258/11.5)*x       - we multiply both sides of the equation by x
100=22.434782608696*x       - we divide both sides of the equation by (22.434782608696) to get x
100/22.434782608696=x
4.4573643410853=x
x=4.4573643410853

now we have:
11.5 is 4.4573643410853% of 258
