12 is what percent of 1807 - 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 1807 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 1807, so we can write it down as 100%=1807.
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%=1807
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%=1807/12
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 1807

100%/x%=1807/12
(100/x)*x=(1807/12)*x       - we multiply both sides of the equation by x
100=150.58333333333*x       - we divide both sides of the equation by (150.58333333333) to get x
100/150.58333333333=x
0.66408411732153=x
x=0.66408411732153

now we have:
12 is 0.66408411732153% of 1807
