Splitting Tasks - Predecessors

[ProjectScotland]

Hi everyone, first time poster.



I am new to Project and and still trying to learn the ropes. Sorry if my question has a simple solution but I cant for the life of me find it anywhere.

So say I have 3 tasks (Task 1, Task 2, Task 3).

Task 3 will take 10 days for completion, split into 6 days(Part 1) and 4 days(Part 2).

Part 1 is dependent on Task 1 being completed and Part 2 is dependent on Task 2 being completed.

My question is how do you assign predecessors to split tasks, so that Part 2 begins when Task 2 is finshed.

Thank You!
