Final answer:
The next fraction in the sequence is 3.
Step-by-step explanation:
To find the next fraction in the sequence, we need to look for a pattern. Let's examine the sequence:
3, 2, 11, 45, 3, 15, 5, ...
Looking at the numbers, it appears that the sequence alternates between smaller and larger numbers. Let's write out the sequence:
3, 2, 11, 45, 3, 15, 5, ...
The pattern seems to be that every fourth number is the same as the first number in the sequence. So, the next fraction in the sequence would be 3.
