Alright so my question is saying ''which expression represents the rectangle below? ''

and its total is 3/2, right? so a purple is shaded in up to 3/4 of the way. then this mother-loving light purple shade comes in and trips me up and goes all the way to 5/4. here are me options for the question above:

a. 2/3 x 5/4

b .10/15 x 5/15

c. 3/4 x 3/2

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
