What is 2.25 percent of 10.9 - 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 10.9 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 10.9 is 100%, so we can write it down as 10.9=100%.
4. We know, that x is 2.25% of the output value, so we can write it down as x=2.25%.
5. Now we have two simple equations:
1) 10.9=100%
2) x=2.25%
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:
10.9/x=100%/2.25%
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 2.25% of 10.9

10.9/x=100/2.25
(10.9/x)*x=(100/2.25)*x       - we multiply both sides of the equation by x
10.9=44.444444444444*x       - we divide both sides of the equation by (44.444444444444) to get x
10.9/44.444444444444=x
0.24525=x
x=0.24525

now we have:
2.25% of 10.9=0.24525
