What is 11.5 percent of 345.25 - 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 345.25 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 345.25 is 100%, so we can write it down as 345.25=100%.
4. We know, that x is 11.5% of the output value, so we can write it down as x=11.5%.
5. Now we have two simple equations:
1) 345.25=100%
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:
345.25/x=100%/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 what is 11.5% of 345.25

345.25/x=100/11.5
(345.25/x)*x=(100/11.5)*x       - we multiply both sides of the equation by x
345.25=8.695652173913*x       - we divide both sides of the equation by (8.695652173913) to get x
345.25/8.695652173913=x
39.70375=x
x=39.70375

now we have:
11.5% of 345.25=39.70375
