12 is what percent of 150.2 - 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 150.2 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 150.2, so we can write it down as 100%=150.2.
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%=150.2
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%=150.2/12
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 150.2

100%/x%=150.2/12
(100/x)*x=(150.2/12)*x       - we multiply both sides of the equation by x
100=12.516666666667*x       - we divide both sides of the equation by (12.516666666667) to get x
100/12.516666666667=x
7.9893475366178=x
x=7.9893475366178

now we have:
12 is 7.9893475366178% of 150.2
