12.29 is what percent of 10400 - 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 10400 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 10400, so we can write it down as 100%=10400.
4. We know, that x% equals 12.29 of the output value, so we can write it down as x%=12.29.
5. Now we have two simple equations:
1) 100%=10400
2) x%=12.29
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%=10400/12.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.29 is what percent of 10400

100%/x%=10400/12.29
(100/x)*x=(10400/12.29)*x       - we multiply both sides of the equation by x
100=846.21643612693*x       - we divide both sides of the equation by (846.21643612693) to get x
100/846.21643612693=x
0.11817307692308=x
x=0.11817307692308

now we have:
12.29 is 0.11817307692308% of 10400
