28.2 is what percent of 308 - 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 308 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 308, so we can write it down as 100%=308.
4. We know, that x% equals 28.2 of the output value, so we can write it down as x%=28.2.
5. Now we have two simple equations:
1) 100%=308
2) x%=28.2
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%=308/28.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.2 is what percent of 308

100%/x%=308/28.2
(100/x)*x=(308/28.2)*x       - we multiply both sides of the equation by x
100=10.921985815603*x       - we divide both sides of the equation by (10.921985815603) to get x
100/10.921985815603=x
9.1558441558442=x
x=9.1558441558442

now we have:
28.2 is 9.1558441558442% of 308
