231.49 is what percent of 1912.4 - 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 1912.4 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 1912.4, so we can write it down as 100%=1912.4.
4. We know, that x% equals 231.49 of the output value, so we can write it down as x%=231.49.
5. Now we have two simple equations:
1) 100%=1912.4
2) x%=231.49
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%=1912.4/231.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 231.49 is what percent of 1912.4

100%/x%=1912.4/231.49
(100/x)*x=(1912.4/231.49)*x       - we multiply both sides of the equation by x
100=8.2612639854853*x       - we divide both sides of the equation by (8.2612639854853) to get x
100/8.2612639854853=x
12.104685212299=x
x=12.104685212299

now we have:
