A clock is divided into 12 segments. From 12 to 9 is 9 segments out of 12. 9/12 = 3/4.

AI explanation

A full clockwise revolution of the hour hand on a clock represents 12 hours. When moving from 12 to 9, the hour hand covers 9 of these 12 hours. Setting this up as a fraction gives 9 over 12, which simplifies to 3/4.
