Identify the Number that Completes the Inequality: 560,979 < ? < 561,949

To solve this problem, let's verify which number fits within the range.

• We are given the inequality: $560,979 < \Box < 561,949$.
• We must find a number that satisfies this inequality.

Now, examining each choice:

• Choice 1: $561,980$ - This number is greater than $561,949$, so it does not satisfy the condition.
• Choice 2: $561,999$ - This number is also greater than $561,949$, so it again does not satisfy the condition.
• Choice 3: $561,003$ - This number is greater than $560,979$ and less than $561,949$, thus it satisfies the condition.
• Choice 4: $560,003$ - This number is less than $560,979$, and thus it does not satisfy the condition.

Based on the analysis of each choice, the number that falls within the specified range is:

Therefore, the solution to the problem is $561,003$.
