123.6 is what percent of 1131 - 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 1131 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 1131, so we can write it down as 100%=1131.
4. We know, that x% equals 123.6 of the output value, so we can write it down as x%=123.6.
5. Now we have two simple equations:
1) 100%=1131
2) x%=123.6
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%=1131/123.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 123.6 is what percent of 1131

100%/x%=1131/123.6
(100/x)*x=(1131/123.6)*x       - we multiply both sides of the equation by x
100=9.1504854368932*x       - we divide both sides of the equation by (9.1504854368932) to get x
100/9.1504854368932=x
10.928381962865=x
x=10.928381962865

now we have:
123.6 is 10.928381962865% of 1131
