To determine the whole number and the rational number to the nearest half that \(\sqrt{105}\) is between, we first need to calculate \(\sqrt{105}\).
Calculating \(\sqrt{105}\):
-
Find the approximate square root:
- We know that \(10^2 = 100\) and \(11^2 = 121\). Thus, \(\sqrt{105}\) must be between 10 and 11.
-
To get a more precise estimate, we can try the midpoint:
- \(10.2^2 = 104.04\) (which is less than 105)
- \(10.3^2 = 106.09\) (which is more than 105)
This shows that \(10.2 < \sqrt{105} < 10.3\).
For a more fine-tuned approximation, we can compute \(\sqrt{105}\) using a calculator, which gives approximately:
\[ \sqrt{105} \approx 10.246 \]
Now we want to find the whole number and the rational number to the nearest half that \(\sqrt{105}\) is between.
- The whole number below \(\sqrt{105} \approx 10.246\) is 10.
- The whole number above is 11.
Now consider the nearest half:
- The nearest half to \(10.246\) is \(10.5\).
In summary: \(\sqrt{105}\) is between the whole numbers \(10\) and \(11\) and the rational number to the nearest half is \(10.5\).
Thus, we have:
- Whole number: \(10\)
- Rational number to the nearest half: \(10.5\)
