Answer:
-3 \frac{3}{7} 

Explanation:
\frac{-24}{7} = -3 \frac{3}{7} 
So first make the improper fraction into a mixed number by taking out all the whole numbers from the numerator (3) and making sure the proper sign is in front of the answer (- 3) your remainder is the original numerator minus the product of the answer times the denominator: 24 - (3 • 7) = 24 - 21 = 3. Rewrite the mixed number.
