To solve this problem, we need to round each number in the middle column to the nearest 10 and the nearest 100.
Rules for Rounding:
*
To the nearest 10: Look at the ones digit (the last number). If it is 5 or more, round up. If it is 4 or less, round down (keep the tens digit the same).
*
To the nearest 100: Look at the tens digit (the middle number). If it is 5 or more, round up. If it is 4 or less, round down (keep the hundreds digit the same).
Let's go through each number:
1.
725
* Nearest 10: The ones digit is 5. Round up. $725 \rightarrow 730$.
* Nearest 100: The tens digit is 2. Round down. $725 \rightarrow 700$.
2.
803
* Nearest 10: The ones digit is 3. Round down. $803 \rightarrow 800$.
* Nearest 100: The tens digit is 0. Round down. $803 \rightarrow 800$.
3.
80
* Nearest 10: The ones digit is 0. It stays the same. $80 \rightarrow 80$.
* Nearest 100: The tens digit is 8. Round up. $80 \rightarrow 100$.
4.
77
* Nearest 10: The ones digit is 7. Round up. $77 \rightarrow 80$.
* Nearest 100: The tens digit is 7. Round up. $77 \rightarrow 100$.
5.
513
* Nearest 10: The ones digit is 3. Round down. $513 \rightarrow 510$.
* Nearest 100: The tens digit is 1. Round down. $513 \rightarrow 500$.
6.
328
* Nearest 10: The ones digit is 8. Round up. $328 \rightarrow 330$.
* Nearest 100: The tens digit is 2. Round down. $328 \rightarrow 300$.
7.
144
* Nearest 10: The ones digit is 4. Round down. $144 \rightarrow 140$.
* Nearest 100: The tens digit is 4. Round down. $144 \rightarrow 100$.
8.
31
* Nearest 10: The ones digit is 1. Round down. $31 \rightarrow 30$.
* Nearest 100: The tens digit is 3. Round down. $31 \rightarrow 0$ (or just leave blank if 0 isn't expected, but mathematically it is 0). Usually, for single-digit rounding to 100, it rounds to 0. Let's write 0.
9.
659
* Nearest 10: The ones digit is 9. Round up. $659 \rightarrow 660$.
* Nearest 100: The tens digit is 5. Round up. $659 \rightarrow 700$.
10.
314
* Nearest 10: The ones digit is 4. Round down. $314 \rightarrow 310$.
* Nearest 100: The tens digit is 1. Round down. $314 \rightarrow 300$.
