    9 boards

    Step-by-step explanation:

    2/3 of the porch = 6 boards

    so to figure out how much one third of the porch needs you find half of what it takes to fill in 2/3 of the porch and you get 3.

    so 3=1/3 of the porch

    then you simply do 3times 3 or 3+3+3 and you get 9

    so it takes 9 boards to fill the whole porch
