    Hi Anonymous ,
    Here are the pics, might by in reverse order. 

    Groupby to get your sums, then divide by 12 to get your division, the use conditional col to decide which col to use.  Then delete intermediate columns.

    Let me know if you have any questions.

    If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos 👍are nice too.

You can do this all in a single aggregation within the Table.Group function:

 

let
    Source = Excel.CurrentWorkbook(){[Name="Table3"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{
        {"ACT/FC", type text}, {"MTH", Int64.Type}, {"TYPE", type text}, {"PRICE", Int64.Type}}),
    
    group = Table.Group(#"Changed Type","MTH",{
        "PRICE", each 
            if List.Contains({9..11},[MTH]{0}) 
                then List.Sum([PRICE]) 
                else List.Sum([PRICE])/12, type number
    })
in
    group
