Question

Natasha watched 1/3 of a movie in the morning, and she watched some more at night. By the end of the day, she still had 2/5 of the movie left to watch. How much of the movie did Natasha watch at night?

Answer 1

Natasha watched 4/15 of the movie at night.

Step-by-step explanation:

First find the Least Common Denominators.
1/3 becomes 5/15
2/5 become 6/15

(If you want to learn about Least Common Denominators, it’s very easy information to find online)

Then subtract 6 from the denominator.
15 - 6 = 9

So 9/15 is the amount of the movie she watched on that day. If she watched 5/15 in the morning: 9 - 5 = 4.

Natasha watched 4/15 of the movie at night.
