What is 11.5 percent of 168 - 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 168 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 168 is 100%, so we can write it down as 168=100%.
4. We know, that x is 11.5% of the output value, so we can write it down as x=11.5%.
5. Now we have two simple equations:
1) 168=100%
2) x=11.5%
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:
168/x=100%/11.5%
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 11.5% of 168

168/x=100/11.5
(168/x)*x=(100/11.5)*x       - we multiply both sides of the equation by x
168=8.69565217391*x       - we divide both sides of the equation by (8.69565217391) to get x
168/8.69565217391=x
19.32=x
x=19.32

now we have:
11.5% of 168=19.32
