What is 350000000 percent of 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 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 12 is 100%, so we can write it down as 12=100%.
4. We know, that x is 350000000% of the output value, so we can write it down as x=350000000%.
5. Now we have two simple equations:
1) 12=100%
2) x=350000000%
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:
12/x=100%/350000000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 350000000% of 12

12/x=100/350000000
(12/x)*x=(100/350000000)*x       - we multiply both sides of the equation by x
12=2.8571428571429E-7*x       - we divide both sides of the equation by (2.8571428571429E-7) to get x
12/2.8571428571429E-7=x
42000000=x
x=42000000

now we have:
350000000% of 12=42000000
