Using a number line, what whole number and rational number to the nearest half is 10−−√

10−−√ is between 3 and

4.

To find the whole number and rational number to the nearest half that is between 3 and √10, let's use a number line.

First, we know that √10 is approximately 3.16. So, let's mark √10 on the number line.

```
0 1 2 3 4
√10
```

Next, we need to find the whole number and rational number to the nearest half between 3 and √10.

The whole number nearest to √10 is 3.

Next, let's find the rational number to the nearest half that is between 3 and √10. Since √10 is approximately 3.16, the nearest half would be 3.5.

Therefore, the whole number to the nearest half that is between 3 and √10 is 3, and the rational number to the nearest half is 3.5.
