Answer:
4 24/135
Explanation:
There are two fractions here, one with denominator 9 and the other with denominator 15. The LCD is thus (9)(15) = 135.
Thus, 10 1/9 - 5 14/15 = 10 15/135 - 5 126/135
or
10 15/135
- 5 126/135
------------------
Since 126/135 is larger than 15/135, we must borrow:
10 15/135 → 9 150/135
- 5 126/135 → -5 126/135
-------------------
4 24/135 → This is the actual difference.
