12 is what percent of 2850000 - 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 2850000 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 2850000, so we can write it down as 100%=2850000.
4. We know, that x% equals 12 of the output value, so we can write it down as x%=12.
5. Now we have two simple equations:
1) 100%=2850000
2) x%=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%=2850000/12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12 is what percent of 2850000

100%/x%=2850000/12
(100/x)*x=(2850000/12)*x       - we multiply both sides of the equation by x
100=237500*x       - we divide both sides of the equation by (237500) to get x
100/237500=x
0.00042105263157895=x
x=0.00042105263157895

now we have:
12 is 0.00042105263157895% of 2850000
