Hey there! :)

Answer:

-4/7.

Step-by-step explanation:

Convert 1 2/7 to an improper fraction:

1 2/7 --> \frac{9}{7}

Convert -2 1/4 to an improper fraction:

-2 1/4 --> \frac{-9}{4}

Divide by multiplying by the reciprocal:

\frac{9}{7} * \frac{4}{-9}= \frac{9*4}{7*(-9)}= \frac{-4}{7}

Therefore, 1 2/7 divided by -2 1/4 equals -4/7.
