To write an equation for the sentence "the difference of 12w and -9 is -22," we start by interpreting the phrase "the difference of 12w and -9" as \( 12w - (-9) \), which simplifies to \( 12w + 9 \). Thus, the equation becomes:
\[ 12w + 9 = -22 \]

To order the numbers \(-\frac{7}{4}\), \(\frac{3}{4}\), \(\frac{4}{3}\), and \(-2\frac{1}{4}\) from least to greatest, we'll first convert the mixed number into an improper fraction.
- \(-2\frac{1}{4} = -\frac{8}{4} - \frac{1}{4} = -\frac{9}{4}\)
Now we have:
- \(-\frac{9}{4}\)
- \(-\frac{7}{4}\)
- \(\frac{3}{4}\)
- \(\frac{4}{3}\)
Next, we need to order these:
- \(-\frac{9}{4} \approx -2.25\)
- \(-\frac{7}{4} \approx -1.75\)
- \(\frac{3}{4} = 0.75\)
- \(\frac{4}{3} \approx 1.33\)
Now, ordering these from least to greatest gives:
\[ -\frac{9}{4}, -\frac{7}{4}, \frac{3}{4}, \frac{4}{3} \]
So the final ordered list is: \(-2\frac{1}{4}, -\frac{7}{4}, \frac{3}{4}, \frac{4}{3}\) from least to greatest.
