Answer:
The answer is D
Step-by-step explanation:
first you have to find the same denominator
the denominator will be 30 because 5×6=30 same with 6×5=30
and whatever you do to the bottom you do to the top so 4×6=24 and 7×5= 35
so its 35/30- 24/30= 11/30 so 7/6-4/5=35/30-24/30 is 11/30=11/30 which is correct.
