Collin is making a bulletin board and note center. he is using square dry-erase tiles .one of every 3 squares will be a cork square .if he uses 12 squares for the note center how many will be cork square s

This question tells us that after every three squares, we will place a cork square. So there are 3 normal squares for every cork square. We are also told that there are a total of 12 squares. If we divide the total squares by the number of normal squares for every cork square, we obtain the number of cork squares. 12 / 3 = 4. So there are 4 cork squares.

Why are u not just putting the numbers this is to much
