What is 8 percent of 38.97 - 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 38.97 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 38.97 is 100%, so we can write it down as 38.97=100%.
4. We know, that x is 8% of the output value, so we can write it down as x=8%.
5. Now we have two simple equations:
1) 38.97=100%
2) x=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:
38.97/x=100%/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 8% of 38.97

38.97/x=100/8
(38.97/x)*x=(100/8)*x       - we multiply both sides of the equation by x
38.97=12.5*x       - we divide both sides of the equation by (12.5) to get x
38.97/12.5=x
3.1176=x
x=3.1176

now we have:
8% of 38.97=3.1176
