- Statement (1) is true. On the number line, the turtle is placed between 2 and 3, closer to 2.5, which matches 2 1/2. The hedgehog is between 3 and 4, closer to 4, matching 3 3/5 (which is 3.6). The rabbit is between 5 and 6, closer to 5, matching 5 1/4 (which is 5.25).
- Statement (2) is true. Adding the hedgehog (3 3/5) and the turtle (2 1/2) gives 3 3/5 + 2 1/2 = 3.6 + 2.5 = 6.1. Since 6.1 is greater than the rabbit’s value of 5.25, the statement “hedgehog + turtle < rabbit” is false. Wait, this contradicts. Let me recalculate: 3 3/5 + 2 1/2 = 18/5 + 5/2 = 36/10 + 25/10 = 61/10 = 6.1. Rabbit is 5 1/4 = 21/4 = 5.25. So 6.1 > 5.25, meaning hedgehog + turtle is NOT less than rabbit. Therefore, statement (2) is false.
- Statement (3) is true. Turtle (2 1/2) + rabbit (5 1/4) = 2.5 + 5.25 = 7.75 = 7 3/4. So this statement is correct.
Therefore, the lie is statement (2).
