Answer:

960

Explanation:

If 1/12 were absent, then 11/12 were present.

If 1/5 of those were gone, then 4/5 of those were present.

(11/12)(4/5)enrollment = 704 . . . 4/5 of 11/12 of the enrollment is 704 students

(11/15)enrollment = 704 . . . . . . simplify

enrollment = 704(15/11) = 960 . . . . . multiply by 15/11

960 students are enrolled at Central High.
