Hours worked 7 1/4 convert to hour and minutes, 6 3/4 convert to hr and minutes, 5 1/5 convert to hr& minutes, 6 1/10 convert to hr & minutes

7 hours 15 minutes, 6 hours 45 minutes, 5 hours 12 minutes, 6 hours 6 minutes

Step-by-step explanation:

7 1/4 hours = 7 hours + 1/4 × 60 = 7 hours 15 minutes

6 3/4 hours = 6 hours +3/4 × 60 = 6 hrs 45 mins.

5 1/5 hours = 5 hours + 1/5 × 60 = 5 hrs 12 mins.

6 1/10 hours = 6 hours + 1/10 × 60 = 6 hours 10 mins.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
