What is 0.8 percent of 1238.21 - 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 1238.21 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 1238.21 is 100%, so we can write it down as 1238.21=100%.
4. We know, that x is 0.8% of the output value, so we can write it down as x=0.8%.
5. Now we have two simple equations:
1) 1238.21=100%
2) x=0.8%
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:
1238.21/x=100%/0.8%
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 0.8% of 1238.21

1238.21/x=100/0.8
(1238.21/x)*x=(100/0.8)*x       - we multiply both sides of the equation by x
1238.21=125*x       - we divide both sides of the equation by (125) to get x
1238.21/125=x
9.90568=x
x=9.90568

now we have:
0.8% of 1238.21=9.90568
