PLS HELP IF U CAN 6TH GARDE MATH TEST GRADE ANSWER BOTH PLSS

If jaime wants to find 60% of 320, which table should he use?

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?

Hi, can anyone show me how to do this problem? 100 points for this. in advance
