Answer: 9 4/5

Explanation: First make the mixed numbers improper fractions.
-2 4/5 would be -14/7 because -2 x 5 + (-4) is -14. -3 1/2 is -7/2 because -3 x 2 + (-1).

Now times both the denominators and numerators. -14 x -7 is 98 and 5 x 2 is 10. The improper fraction is 98/10

Now make the improper fraction a mixed number which would be 9 4/5. 10 goes into 98 9 times and there is 8 left, keep the denominator 10.
8/10 isn’t simplified as you divide both by 2 which is 4/5

Don’t forget your mixed number and the answer is 9 4/5
