Answer:
see below
Explanation:
We want to get common denominators to compare
2/3 and 4/5 have a common denominator of 15
2/3 *5/5 = 10/15
4/5 *3/3 = 12/15
These are not the same fraction so they are not equivalent
2/3 and 5/6 have a common denominator of 6
2/3 *2/2 = 4/6
5/6 *1/1 = 5/6
These are not the same fraction so they are not equivalent
