Question

What is the product of −412 and 212 ? Enter your answer as a mixed number, in simplified form, in the box.

Answer 1

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:


`(-4 (1)/(2) ).(2 (1)/(2) ) = (-4 - (1)/(2) ).(2+ (1)/(2) )=(- (9)/(2) ).( (5)/(2))=- (45)/(4) = -( (44 + 1)/(4) ) = - 11 (1)/(4)`

Answer: - 11 1/4
