12.28 is what percent of 18.49 - 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 18.49 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 18.49, so we can write it down as 100%=18.49.
4. We know, that x% equals 12.28 of the output value, so we can write it down as x%=12.28.
5. Now we have two simple equations:
1) 100%=18.49
2) x%=12.28
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%=18.49/12.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.28 is what percent of 18.49

100%/x%=18.49/12.28
(100/x)*x=(18.49/12.28)*x       - we multiply both sides of the equation by x
100=1.5057003257329*x       - we divide both sides of the equation by (1.5057003257329) to get x
100/1.5057003257329=x
66.414277988102=x
x=66.414277988102

now we have:
12.28 is 66.414277988102% of 18.49
