30.6 is what percent of 144.8 - 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 144.8 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 144.8, so we can write it down as 100%=144.8.
4. We know, that x% equals 30.6 of the output value, so we can write it down as x%=30.6.
5. Now we have two simple equations:
1) 100%=144.8
2) x%=30.6
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%=144.8/30.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.6 is what percent of 144.8

100%/x%=144.8/30.6
(100/x)*x=(144.8/30.6)*x       - we multiply both sides of the equation by x
100=4.7320261437908*x       - we divide both sides of the equation by (4.7320261437908) to get x
100/4.7320261437908=x
21.132596685083=x
x=21.132596685083

now we have:
30.6 is 21.132596685083% of 144.8
