To order the numbers from least to greatest, we first need to convert them into comparable forms, such as decimals:

• $6.7$ is already a decimal.
• $8 \frac{4}{5} = 8 + \frac{4}{5} = 8 + 0.8 = 8.8$
• $7 \frac{1}{4} = 7 + \frac{1}{4} = 7 + 0.25 = 7.25$

Now, we compare the decimals:

• $6.7$
• $7.25$
• $8.8$

Thus, the order from least to greatest is:

$6.7, 7.25, 8.8$
