When dividing by a fraction change division to multiplication and flip the second fraction over.
3/4 / 5/6 = 3/4 x 6/5
Now multiply the two top numbers together and the two bottom numbers together
3/4 x 6/5 = (3 x 6) / 4 x 5) = 18/20
Both numbers are even and can be reduced by dividing by 2
18/20 = 9/10
Answer: 9/10
