Answer:
5/6
Explanation:
(2/3) / (4/5) = (2/3) * (5/4) Rock times roll, which means keep the first fraction the same ("rock"), change the division to "times", and "roll" the second fraction.
= (1/3) * (5/2) Simplify the 2 and the /4 since they are both even
= (1*5)/(2*3) Multiply the numerators together and the denominators together
= 5/6
