1 of 3 will be cork.

1/3 * 12 = 4

Answer: He will use 4 cork tiles.

Answer 2

Hey there!
If we have 12 squares and one of every 3 is a cork square, that means that 1/3 of the squares are cork. Using our keyword "of" meaning multiplication, we have:
1/3 * 12 = 12/3 = 4 cork squares
Hope this helps!
