1311.84 is what percent of 911 - 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 911 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 911, so we can write it down as 100%=911.
4. We know, that x% equals 1311.84 of the output value, so we can write it down as x%=1311.84.
5. Now we have two simple equations:
1) 100%=911
2) x%=1311.84
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%=911/1311.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1311.84 is what percent of 911

100%/x%=911/1311.84
(100/x)*x=(911/1311.84)*x       - we multiply both sides of the equation by x
100=0.69444444444444*x       - we divide both sides of the equation by (0.69444444444444) to get x
100/0.69444444444444=x
144=x
x=144

now we have:
1311.84 is 144% of 911
