Answer:
D. 1/4
Explanation:
Add 12 and 36 days to find the total of 48 days.
Then, you know that Jack saw rabbits in his yard for 12 days.
You could put that into a fraction: 12/48 (48 days is the total amount of days, 12 is the number of days he saw rabbits in his yard.)
Last, you simplify the fraction into 1/4 because they have the Greatest Common Factor of 4.
