To find the whole number and the rational number to the nearest half that \( \sqrt{70} \) is between, we first need to estimate \( \sqrt{70} \).
We know that:
- \( 8^2 = 64 \)
- \( 9^2 = 81 \)
Since \( 64 < 70 < 81 \), it follows that:
\[ 8 < \sqrt{70} < 9 \]
Next, we can get a better estimate of \( \sqrt{70} \) by calculating it:
\[ \sqrt{70} \approx 8.37 \]
Now let's find the nearest half. The nearest halves around \( 8.37 \) are \( 8.5 \) and \( 8.0 \). Since \( 8.37 \) is closer to \( 8.5 \), we can round \( \sqrt{70} \) to:
\[ 8.37 \approx 8.5 \]
Therefore, \( \sqrt{70} \) is between the whole number \( 8 \) and the rational number \( 8.5 \).
In conclusion, \( \sqrt{70} \) is:
- Between the whole number: 8
- And the rational number to the nearest half: 8.5
