Answer 2

Identifying Three-Digit Numbers with Only 4 and 0

To identify all three-digit numbers that can be represented using only the digits 4 and 0, we can consider the possible combinations of these digits in the hundreds, tens, and units places.

Hundreds Place: The hundreds place can only be filled with 4, as 0 cannot be used in the hundreds place. Therefore, the hundreds place can only be 4.

Tens Place: Both 4 and 0 can be used in the tens place. Therefore, the tens place can be either 4 or 0.

Units Place: Similar to the tens place, both 4 and 0 can be used in the units place. Therefore, the units place can be either 4 or 0.

Conclusion

By considering the combinations of 4 and 0 in the hundreds, tens, and units places, we can identify the following three-digit numbers that can be represented using only the digits 4 and 0: - 400 - 404

These are the only three-digit numbers that can be formed using only the digits 4 and 0.
