Problem Statement: Round the numbers 2,864, 3,058, and 4,315 to the nearest tens, hundreds.

Solution Guide:
- When rounding to the nearest tens, compare the units digit with 5. If the units digit is less than 5, round down; otherwise, round up.

Problem Statement: Robot, Viet, and Mai visited a farm together. Robot counted 1,242 chickens. When rounding to the nearest tens:

Mai says: 'The farm has around 1,240 chickens'.
Viet says: 'The farm has around 1,250 chickens'.
In your opinion, who is correct?

Solution Guide: When rounding numbers to the nearest tens, compare the units digit with 5. If the units digit is less than 5, round down; otherwise, round up.

Answer:
The number 1,242 has a units digit of 2. Since 2 is less than 5, according to the rule for rounding numbers to the nearest tens, we round down. Therefore, the number 1242 is rounded to the nearest tens as 1240.

So Mai is correct.
