Answer:
2:45
Step-by-step explanation:
the tiny hand on the clock represents the hour while the long hand on the clock represents the minute(s).
that being said, the tiny hand is between 2 and 3-we can eliminate c and d.
look at the minute hand. it is on 9, which means 45
we can cross out 3:45 as the hour hand is not between 3 and 4.
this leaves us with 2:45
hope this helps :)

Solve for k by multiplying both sides by 9.
k = 81
