What is 22.1 percent of 15.2 - 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 15.2 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 15.2 is 100%, so we can write it down as 15.2=100%.
4. We know, that x is 22.1% of the output value, so we can write it down as x=22.1%.
5. Now we have two simple equations:
1) 15.2=100%
2) x=22.1%
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:
15.2/x=100%/22.1%
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 22.1% of 15.2

15.2/x=100/22.1
(15.2/x)*x=(100/22.1)*x       - we multiply both sides of the equation by x
15.2=4.5248868778281*x       - we divide both sides of the equation by (4.5248868778281) to get x
15.2/4.5248868778281=x
3.3592=x
x=3.3592

now we have:
22.1% of 15.2=3.3592
