A basketball player is 623 feet tall. His infant son is 14 as tall. How tall is his son?

The son is 14 times shorter than the basketball player, so the son is 623/14 = <<623/14=44.5>>44.5 feet tall. Answer: \boxed{44.5}.

To find out how tall the basketball player's son is, you'll need to calculate 14% of the player's height:

Height of the basketball player = 623 feet
Height of the son = 14% of the player's height

To find 14% of the player's height, you can convert the percentage to a decimal by dividing it by 100:

14% ÷ 100 = 0.14

Now, multiply the player's height by the decimal:

623 feet × 0.14 = 87.22 feet

Therefore, the son is approximately 87.22 feet tall.
