2.8 is what percent of 37.12 - 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 37.12 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 37.12, so we can write it down as 100%=37.12.
4. We know, that x% equals 2.8 of the output value, so we can write it down as x%=2.8.
5. Now we have two simple equations:
1) 100%=37.12
2) x%=2.8
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%=37.12/2.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.8 is what percent of 37.12

100%/x%=37.12/2.8
(100/x)*x=(37.12/2.8)*x       - we multiply both sides of the equation by x
100=13.257142857143*x       - we divide both sides of the equation by (13.257142857143) to get x
100/13.257142857143=x
7.5431034482759=x
x=7.5431034482759

now we have:
2.8 is 7.5431034482759% of 37.12
