what whole number and rational number to the nearest half is 105−−−√ between?

To find the whole number and rational number (to the nearest half) that is between $\sqrt{105}$, we need to find the two nearest perfect squares to $105$.

$10^2 = 100$ and $11^2 = 121$, so $105$ is between the perfect squares of $100$ and $121$.

Taking the square roots, we have $10 < \sqrt{105} < 11$.

In terms of halves, $\frac{10}{1} < \sqrt{105} < \frac{11}{1}$.

Therefore, the whole number and rational number to the nearest half that is between $\sqrt{105}$ is $\boxed{\frac{10}{1}}$.

To find the whole number and rational number to the nearest half that 105√ is between, we can calculate the square root and round it to the nearest half.

Step 1: Calculate the square root of 105.
√105 ≈ 10.246950

Step 2: Round the square root to the nearest half.
Rounding 10.246950 to the nearest half gives us 10.5.

Therefore, the whole number and rational number to the nearest half that 105√ is between are 10 and 10.5, respectively.
