10.4 is what percent of 131.8 - 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 131.8 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 100% equals 131.8, so we can write it down as 100%=131.8.
4. We know, that x% equals 10.4 of the output value, so we can write it down as x%=10.4.
5. Now we have two simple equations:
1) 100%=131.8
2) x%=10.4
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:
100%/x%=131.8/10.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.4 is what percent of 131.8

100%/x%=131.8/10.4
(100/x)*x=(131.8/10.4)*x       - we multiply both sides of the equation by x
100=12.673076923077*x       - we divide both sides of the equation by (12.673076923077) to get x
100/12.673076923077=x
7.8907435508346=x
x=7.8907435508346

now we have:
10.4 is 7.8907435508346% of 131.8
