What is 2.19 percent of 17.75 - 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 17.75 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 17.75 is 100%, so we can write it down as 17.75=100%.
4. We know, that x is 2.19% of the output value, so we can write it down as x=2.19%.
5. Now we have two simple equations:
1) 17.75=100%
2) x=2.19%
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:
17.75/x=100%/2.19%
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 2.19% of 17.75

17.75/x=100/2.19
(17.75/x)*x=(100/2.19)*x       - we multiply both sides of the equation by x
17.75=45.662100456621*x       - we divide both sides of the equation by (45.662100456621) to get x
17.75/45.662100456621=x
0.388725=x
x=0.388725

now we have:
2.19% of 17.75=0.388725
