Cut into quarters, then split each quarter into three. A clock face already shows twelfths: every hour mark is one twelfth of the way around.

Common mix-ups with 5/12

It's not 12/5

Swapping the numbers changes everything. 5/12 is less than one whole; 12/5 is more than one whole. The bottom number always says how many equal parts make up the whole.

It's not 5/7

A pie with 5 filled and 7 empty is not 5/7. That compares the filled part to the empty part. The bottom number counts all 12 parts, filled or not.
