What is 13 percent of 198 - 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 198 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 198 is 100%, so we can write it down as 198=100%.
4. We know, that x is 13% of the output value, so we can write it down as x=13%.
5. Now we have two simple equations:
1) 198=100%
2) x=13%
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:
198/x=100%/13%
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 13% of 198

198/x=100/13
(198/x)*x=(100/13)*x       - we multiply both sides of the equation by x
198=7.69230769231*x       - we divide both sides of the equation by (7.69230769231) to get x
198/7.69230769231=x
25.74=x
x=25.74

now we have:
13% of 198=25.74
