Sabrina received total 371 text messages

5/9 of them from Colleges

2/7 of them from family member

Total text messages from Colleges and

family member = $$({5 \over 9} + {2 \over 5 })371$$

=$$({35 + 18\over 63})371$$

=$$({53 \over 63}) 371 = 312 * 11$$

Remaining texts as 371 - 312

= 59
She got 1/3 of remaining texts from Teri

i.e, 59 * 1/5 = 11.8 ~ 12

She got 12 messages from Teri.
