To list the numbers shown in the number line in increasing order and identify their decimal approximations using 3.14 as an approximation for 𝜋, we will calculate each number:

  1. Square root of 12: \[ \sqrt{12} \approx 3.464 \]

  2. : \[ -3.14 \]

  3. π/2: \[ \frac{3.14}{2} \approx 1.57 \]

  4. Square root of 23: \[ \sqrt{23} \approx 4.796 \]

  5. : \[ 2 \times 3.14 \approx 6.28 \]

  6. Square root of 47: \[ \sqrt{47} \approx 6.855 \]

Now that we have the approximate values for each number, we can fill in the blanks in increasing order as you requested:

  • square root of 12 (≈ 3.464) < -π (≈ -3.14) < 1.57 < π/2 < square root of 23 (≈ 4.796) < 3.446 < square root of 47 (≈ 6.855) < 6.28 < 4.79 < 6.28 < 6.85 < 2π (≈ 6.28)

Now arranging them correctly in increasing order, the final sequence with approximations filled in is:

  • square root of 12 < -3.14 < 1.57 < π/2 < 3.446 < square root of 23 < 4.796 < 6.28 < 6.855 < 2π

Thus, the completed sentence in increasing order is:

-square root of 12 < -3.14 < 1.57 < π/2 < square root of 23 < 4.79 < 3.446 < square root of 47 < 6.28 < 6.85 < 2π
