Answer:

Step-by-step explanation:
The product of a scalar and a matrix is a matrix of the <em>same dimensions</em>, each term having been multiplied by the scalar. The only answer choice with the same dimensions as the original is the last choice.
The final answer will be negative because a positive divided by a negative is a negative. Let's condense this into...
-(158÷135)
How many 135s are in 158? One, because two "135s" (which is 270) is greater than 158, but 135 isn't. So we know the mixed number will be 1 + (a fraction). What's the Fraction? We can find this by subtracting 135 from 158, (158 - 135) = 23. The fraction is 23/158.
The answer is, -1, 23/158.
