To determine which range the number \( \sqrt{58} \) falls between, we first calculate \( \sqrt{58} \).

Calculating \( \sqrt{58} \):

  • We know that \( 7^2 = 49 \) and \( 8^2 = 64 \).
  • This means \( \sqrt{58} \) is between 7 and 8.

Next, we can estimate \( \sqrt{58} \) further:

To find a more precise value, we can approximate:

Since \( 7.5^2 = 56.25 \) and \( 8^2 = 64 \), this shows:

  • \( 7.5^2 < 58 < 8^2 \)
  • Therefore, \( \sqrt{58} \) is between 7.5 and 8.

Now let's identify the rational number to the nearest half.

Since \( 7.5 < \sqrt{58} < 8 \), it rounds to 7.5 when considering to the nearest half.

Thus, the whole number is 7, and the rational number to the nearest half is 7.5.

So the final answer is:

between 7.5 and 8.
