12 is what percent of 197000000 - 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 197000000 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 197000000, so we can write it down as 100%=197000000.
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%=197000000
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%=197000000/12
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 197000000

100%/x%=197000000/12
(100/x)*x=(197000000/12)*x       - we multiply both sides of the equation by x
100=16416666.666667*x       - we divide both sides of the equation by (16416666.666667) to get x
100/16416666.666667=x
6.0913705583756E-6=x
x=6.0913705583756E-6

now we have:
12 is 6.0913705583756E-6% of 197000000
