Given that the statement requires the answer as a mixed number, it is evident that the factors involve fractions and not actually - 412 and 212.
It seems that the two factors are - 4 + 1/2 and 2 + 1/2.
Let's use latex for better underestanding:
[tex](-4 \frac{1}{2} ).(2 \frac{1}{2} ) = (-4 - \frac{1}{2} ).(2+ \frac{1}{2} )=(- \frac{9}{2} ).( \frac{5}{2})=- \frac{45}{4} = -( \frac{44 + 1}{4} ) = - 11 \frac{1}{4} [/tex]
Answer: - 11 1/4
