What is 7.176 percent of 138 - 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 138 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 138 is 100%, so we can write it down as 138=100%.
4. We know, that x is 7.176% of the output value, so we can write it down as x=7.176%.
5. Now we have two simple equations:
1) 138=100%
2) x=7.176%
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:
138/x=100%/7.176%
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 7.176% of 138

138/x=100/7.176
(138/x)*x=(100/7.176)*x       - we multiply both sides of the equation by x
138=13.935340022297*x       - we divide both sides of the equation by (13.935340022297) to get x
138/13.935340022297=x
9.90288=x
x=9.90288

now we have:
7.176% of 138=9.90288
