308.5 is what percent of 1506 - 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 1506 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 1506, so we can write it down as 100%=1506.
4. We know, that x% equals 308.5 of the output value, so we can write it down as x%=308.5.
5. Now we have two simple equations:
1) 100%=1506
2) x%=308.5
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%=1506/308.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 308.5 is what percent of 1506

100%/x%=1506/308.5
(100/x)*x=(1506/308.5)*x       - we multiply both sides of the equation by x
100=4.8816855753647*x       - we divide both sides of the equation by (4.8816855753647) to get x
100/4.8816855753647=x
20.484727755644=x
x=20.484727755644

now we have:
308.5 is 20.484727755644% of 1506
