Greedy Algorithm for Fractional and Greedy0

So this is not my homework, i need to learn this for my next exam, so i might need some more detailed explanation with this example.

So this is the assignment , i need to use Greedy algorithm to this matter and show per Iteration how the Object is doing. So i have some Container, it can contain 23kg of thing (Z) and i have 7 different Object. First Object has the Weight of 6 and Value of 5 , Object 2 has the Weight of 14 and Value of 14, etc until Object 7.

This is the first Algorithm, sorry if its in german, but basically its the same algorithm elsewhere ( Greedy Algorithm )

This is the second algorithm. What i understand from this 2 Algorithm is:

1) Fractional will then fraction the total of weight with higher value. For Example we can take 7kg of Object 2 and not fully (14kg)

2) Greedy0 will take full course of Object

If someone can explain to me better, i will really appreciate it. Thanks!
