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

Amount watched at night  by Ingrid = 1/6

Step-by-step explanation:

Let total amount of movie to watch = 1 whole since we are dealing with fractions

Amount of movie watched in the morning = 1/2

Amount watched at night = x

Amount remaining at the end of day = 1/3

So that to find amount watched at night we use

 Total amount of movie to watch - Amount watched in morning and night = Amount remaining to watch

1 - ( 1/2+ x ) = 1/3

1- 1/3 = 1/2 + x

2/3 =1/2+ x

2/3 - 1/2 = x

4-3/6 = x

1/6=X

x= Amount watched at night = 1/6
