To find out how tall the basketball player's son is, we need to calculate 1/4 of the father's height, which is 6 2/3 feet.
First, let's convert 6 2/3 into an improper fraction:
6 2/3 = 6 + 2/3 = (6 * 3 + 2) / 3 = (18 + 2) / 3 = 20/3 feet.
Now, we calculate 1/4 of the father's height:
(1/4) * (20/3) = 20/12 = 5/3 feet.
Now, we can convert 5/3 feet back to a mixed number:
5/3 = 1 2/3 feet.
So, the son is 1 2/3 feet tall.
