Carl worked six and one-half hours on Monday. He worked eight and two-third hours on Tuesday. How many hours did Carl work in all?

Answer: 15 hours and 37 minutes

Step-by-step explanation: 6 and 1/2 hours is 6 hours and 30 mins

8 and 2/3 hours is 8 hours and 67 mins

So 8 hours + 6 hours is 14 hours

Since 67 minutes is over an hour, we're going to take 60 minutes from 67, leaving u with 7 minutes

Add the 60 minutes to the 14 hours and you get 15 hours.

Take the 7 minutes and add it to the 30 minutes and you get 37 minutes.

All together the answer is 15 hours and 37 minutes
