A) For this one, just remember how dividing by negatives work. If one negative, it's negative, two negatives and it's positive. -(18/5) is negative, (-18/-5) is positive, (-18/5) is negative, (18/-5) is negative. This means that (-18/-5) is the one that is not equivalent.
B) Same scenario, but convert the decimals to fractions. 0.75=3/4, so you have -(3/4) in decimal form, (-3/4), (3/-4), -(3/4), and (3/4) in decimal form. Here, (3/4) or 0.75 is the one that is not equivalent as all the others are negative, but this one is positive.
