To solve the equation \((x + 27)^2 / -6 = -3\), we first eliminate the fraction by multiplying both sides by \(-6\):
\[
(x + 27)^2 = -3 \times -6
\]
\[
(x + 27)^2 = 18
\]
Next, we take the square root of both sides:
\[
x + 27 = \pm \sqrt{18}
\]
We can simplify \(\sqrt{18}\):
\[
\sqrt{18} = \sqrt{9 \cdot 2} = 3\sqrt{2}
\]
Now we express the two cases for \(x + 27\):
1. \(x + 27 = 3\sqrt{2}\)
2. \(x + 27 = -3\sqrt{2}\)
Next, we will solve for \(x\) in each case:
1. \(x = 3\sqrt{2} - 27\)
2. \(x = -3\sqrt{2} - 27\)
Now, we can compute \(3\sqrt{2}\):
\[
3\sqrt{2} \approx 3 \times 1.414 \approx 4.242
\]
Thus,
1. \(x \approx 4.242 - 27 \approx -22.758\)
2. \(x \approx -4.242 - 27 \approx -31.242\)
Now, rounding to the nearest hundredth:
1. \(x_1 \approx -22.76\)
2. \(x_2 \approx -31.24\)
The smaller of the two values is:
\[
\boxed{-31.24}
\]
And the other value is:
\[
\boxed{-22.76}
\]
So, the final answer with the smaller value first is:
\[
\boxed{-31.24, -22.76}
\]
\[
(x + 27)^2 = -3 \times -6
\]
\[
(x + 27)^2 = 18
\]
Next, we take the square root of both sides:
\[
x + 27 = \pm \sqrt{18}
\]
We can simplify \(\sqrt{18}\):
\[
\sqrt{18} = \sqrt{9 \cdot 2} = 3\sqrt{2}
\]
Now we express the two cases for \(x + 27\):
1. \(x + 27 = 3\sqrt{2}\)
2. \(x + 27 = -3\sqrt{2}\)
Next, we will solve for \(x\) in each case:
1. \(x = 3\sqrt{2} - 27\)
2. \(x = -3\sqrt{2} - 27\)

\[
3\sqrt{2} \approx 3 \times 1.414 \approx 4.242

2. \(x \approx -4.242 - 27 \approx -31.242\)
Now, rounding to the nearest hundredth:
1. \(x_1 \approx -22.76\)
2. \(x_2 \approx -31.24\)
The smaller of the two values is:
\[
\boxed{-31.24}

And the other value is:
\[
\boxed{-22.76}

So, the final answer with the smaller value first is:
\[
\boxed{-31.24, -22.76}
