What is 18.8 percent of 172 - 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 172 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 172 is 100%, so we can write it down as 172=100%.
4. We know, that x is 18.8% of the output value, so we can write it down as x=18.8%.
5. Now we have two simple equations:
1) 172=100%
2) x=18.8%
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:
172/x=100%/18.8%
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 18.8% of 172

172/x=100/18.8
(172/x)*x=(100/18.8)*x       - we multiply both sides of the equation by x
172=5.3191489361702*x       - we divide both sides of the equation by (5.3191489361702) to get x
172/5.3191489361702=x
32.336=x
x=32.336

now we have:
18.8% of 172=32.336
