5123.54 is what percent of 12896 - 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 12896 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 12896, so we can write it down as 100%=12896.
4. We know, that x% equals 5123.54 of the output value, so we can write it down as x%=5123.54.
5. Now we have two simple equations:
1) 100%=12896
2) x%=5123.54
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%=12896/5123.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5123.54 is what percent of 12896
