Answer:
-(45)/(8)
or
-5\ (5)/(8)

Explanation:

Rewrite each mixed numbers as fractions:


3\ (3)/(4)=((4*3)+3)/(4)=(12+3)/(4)=(15)/(4)\\\\1\  (1)/(2)=((2*1)+1)/(2)=(3)/(2)

Make the multiplication:

Multiply the numerator of the first fraction by the numerator of the second fraction and the denominator of the first fraction by the denominator of the second fraction.


((15)/(4))(-(3)/(2))=-(45)/(8) or
-5\ (5)/(8)
