Answer:
7/12
Explanation:
The problem is asking us to find what fraction of students watch between 0 and 2 hours of TV a day:
The information we have is:
0 - 1 hours = 1/6
1 1/2 - 2 hours = 5/12
We only need this information because it is asking us for 0 to 2 hours.
Now we have to add the fraction of students that watch TV 0-1 hours and the fraction of students watch TV 1 1/2 - 2 hours:
1/6 + 5/12
To be able to solve this we have to have the same denominator and to do it we have to multiply the first fraction by 2:
(1/6) *2 = 2/12
Now we can add:
2/12 + 5/12 = 7/12
We add the numerators and the denominator stays the same.
