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? 1/12 of an hour 3/25 of an hour 3/4 of an hour 11/12 of an hour

The correct answer is 3/4 of an hour

Step-by-step explanation:

Sam spent 5/6 of an hour at the dentist´s office and 1/10 of that time he was in the waiting room. To solve this problem you have to consider that if you want to calculate 1/10 of 5/6, you must multiply both fractions

⇒(5/6) x (1/10) = 5/60 = 1/12. 1/12 of an hour is the time he spent in the waiting room. Then to find the time in another part, you should calculate the difference between 5/6 and 1/12 ⇒ (5/6) - (1/12) = 3/4.

So, he spend 3/4 of an hour at the dentist’s office other than in the waiting room
