    First, I change the contries to variables

    Vietnam - v

    Australia - a

    brazil - b

    new Zealand - n

    v=4a

    b=8a

    a=5n

    brazil is not needed

    plug in 5n for a

    v=4 (5n)

    v=20n

    Vietnam would actually be larger if it takes 20 new zealands for 1 vietnam
