Does anyone know how to do this?

Answer:
The last one for the x column 12.8, and the last two for the y columns are 16 and 64.
Step-by-step explanation:
So you know that you have to multiply 0.8 by 4 to get 3.2, right? If you have to multiply 0.8 by 4, that means that you also have to multiply 4 by 4.
Sorry I'm not a great teacher :/
Hope this helps!
