What is 121.1 percent of 31 - 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 31 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 31 is 100%, so we can write it down as 31=100%.
4. We know, that x is 121.1% of the output value, so we can write it down as x=121.1%.
5. Now we have two simple equations:
1) 31=100%
2) x=121.1%
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:
31/x=100%/121.1%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 121.1% of 31

31/x=100/121.1
(31/x)*x=(100/121.1)*x       - we multiply both sides of the equation by x
31=0.82576383154418*x       - we divide both sides of the equation by (0.82576383154418) to get x
31/0.82576383154418=x
37.541=x
x=37.541

now we have:
121.1% of 31=37.541
