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.
