What is 7.79 percent of 12.38 - 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 12.38 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 12.38 is 100%, so we can write it down as 12.38=100%.
4. We know, that x is 7.79% of the output value, so we can write it down as x=7.79%.
5. Now we have two simple equations:
1) 12.38=100%
2) x=7.79%
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:
12.38/x=100%/7.79%
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 7.79% of 12.38

12.38/x=100/7.79
(12.38/x)*x=(100/7.79)*x       - we multiply both sides of the equation by x
12.38=12.836970474968*x       - we divide both sides of the equation by (12.836970474968) to get x
12.38/12.836970474968=x
0.964402=x
x=0.964402

now we have:
7.79% of 12.38=0.964402
