What is 7.2 percent of 197 - 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 197 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 197 is 100%, so we can write it down as 197=100%.
4. We know, that x is 7.2% of the output value, so we can write it down as x=7.2%.
5. Now we have two simple equations:
1) 197=100%
2) x=7.2%
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:
197/x=100%/7.2%
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 7.2% of 197

197/x=100/7.2
(197/x)*x=(100/7.2)*x       - we multiply both sides of the equation by x
197=13.888888888889*x       - we divide both sides of the equation by (13.888888888889) to get x
197/13.888888888889=x
14.184=x
x=14.184

now we have:
7.2% of 197=14.184
