What is 2.25 percent of 13.75 - 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 13.75 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 13.75 is 100%, so we can write it down as 13.75=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) 13.75=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:
13.75/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 13.75

13.75/x=100/2.25
(13.75/x)*x=(100/2.25)*x       - we multiply both sides of the equation by x
13.75=44.444444444444*x       - we divide both sides of the equation by (44.444444444444) to get x
13.75/44.444444444444=x
0.309375=x
x=0.309375

now we have:
2.25% of 13.75=0.309375
