Plz I need an answer to this ASAP! A piece of wood that is 9 feet long is cut in half lengthwise. Each half is the cut lengthwise into six congruent pieces of wood. What is the length of each of the twelve small pieces of wood

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?
