HELP !!! PLZ

Sam spent 5/6 of an hour at the dentist’s office. He spent 1/10 of the time in the waiting room. How much time did he spend at the dentist’s office other than in the waiting room?
A. 1/12 of an hour
B. 3/25 of an hour
C. 3/4 of an hour
D. 11/12 of an hour

Answer 1

D) 11/12 of an hour

5/6 of an hour is 50 minutes, and 1/10 of that is five minutes

5 is 1/12 of 60 minutes, so it would be 11/12 for the rest
