Use long division to convert 2750 to a decimal.(1 point)

To convert 2750 to a decimal using long division, you need to divide by 1000 (since we want to express it as a decimal).

1. Set up the long division with 2750 divided by 1000.

```
2.75
_________
1000 | 2750
```

2. 1000 goes into 2750 two times (1000 × 2 = 2000).
3. Subtract 2000 from 2750, leaving 750.
4. Bring down a zero, making it 7500.
5. 1000 goes into 7500 seven times (1000 × 7 = 7000).
6. Subtract 7000 from 7500, leaving 500.
7. Bring down another zero, making it 5000.
8. 1000 goes into 5000 five times (1000 × 5 = 5000).
9. Subtract 5000 from 5000, leaving 0.

This means:

2750 ÷ 1000 = 2.75.

Therefore, the decimal conversion of 2750 is **2.75**.
