Answer:
20/30 (2/3)
Step-by-step explanation:
1 5/6 in improper form is 11/6 and 1 2/5 in improper form is 7/5. We need to find an LCM (Least Common Multiple). The LCM in this case is 30. 11/6 times 5 is 55/30 and 7/5 times 6 is 35/30. 55/30 minus 35/30 is 20/30. That could also be simplified to 2/3.
