Let's analyze each comparison to determine which ones are correct:
-
1/2 < 1/5: False. (1/2 is greater than 1/5)
-
3/5 > 3/10: True. (3/5 is greater than 3/10)
-
2/8 < 1/4: True. (2/8 simplifies to 1/4; so they are equal, not less than)
-
5/6 > 2/5: True. (5/6 is greater than 2/5)
-
5/10 > 2/5: False. (5/10 simplifies to 1/2, which is equal to 2/5; so this is incorrect)
So the correct comparisons are:
- 3/5 > 3/10
- 5/6 > 2/5
