307.59 is what percent of 345 - 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 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 345, so we can write it down as 100%=345.
4. We know, that x% equals 307.59 of the output value, so we can write it down as x%=307.59.
5. Now we have two simple equations:
1) 100%=345
2) x%=307.59
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%=345/307.59
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 307.59 is what percent of 345

100%/x%=345/307.59
(100/x)*x=(345/307.59)*x       - we multiply both sides of the equation by x
100=1.1216229396274*x       - we divide both sides of the equation by (1.1216229396274) to get x
100/1.1216229396274=x
89.15652173913=x
x=89.15652173913

now we have:
307.59 is 89.15652173913% of 345
