Tawni watched 3/4 of a movie in 1 1/2 hours. Which is the length of the movie?
ella [17]

Answer:

2 hours.

Step-by-step explanation:

1 1/2 hours is equal to 90 minutes. We can calculate from this that 1/4 of the movie is equal to 30 minutes. To get the answer, we add the missing 1/4 of the movie (equal to 30 minutes) to get a total of 120 minutes, which is equal to two hours.
