Each of the lists below is in order from least to greate \( \mathrm{gr}^{\mathrm{st}} \) and has one number missing. List an example of a value that could correctly complete the blank in each list. 1. \( -\sqrt{49},-\frac{33}{5} \) \( \qquad \) ,\( -6 . \overline{4} \) 2. \( \qquad \) \( , 8.75,8 \frac{4}{5}, \sqrt{81} \) 3. \( -2 \frac{9}{10} \) \( \qquad \) \( ,-2 \frac{3}{5},-2.45 \)

For the first list, the missing number should be between \( -\sqrt{49} \) (which equals -7) and \( -6.\overline{4} \) (which is approximately -6.4). A suitable value is \( -7,5 \). In the second list, the missing number must fall between the empty spot and \( 8 \frac{4}{5} \) (which is equal to 8.8) and \( 8.75 \). A good candidate for this spot could be \( 8.5 \). For the third list, the missing number should be situated between \( -2 \frac{9}{10} \) (which is approximately -2.9) and \( -2 \frac{3}{5} \) (which is equal to -2.6). An example that fits is \( -2.8 \).
