30.12 is what percent of 1115 - 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 1115 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 1115, so we can write it down as 100%=1115.
4. We know, that x% equals 30.12 of the output value, so we can write it down as x%=30.12.
5. Now we have two simple equations:
1) 100%=1115
2) x%=30.12
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%=1115/30.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.12 is what percent of 1115

100%/x%=1115/30.12
(100/x)*x=(1115/30.12)*x       - we multiply both sides of the equation by x
100=37.018592297477*x       - we divide both sides of the equation by (37.018592297477) to get x
100/37.018592297477=x
2.7013452914798=x
x=2.7013452914798

now we have:
30.12 is 2.7013452914798% of 1115
