Hurry please! Johnny said the number 1/3 is irrational because it repeats forever as 0.3333333.

Choose the statement that is true.
A. Johnny is correct because irrational numbers never end.
B. Johnny is correct because 1/3 can be written as a quotient of two integers.
C. Johnny is incorrect because a repeating decimal is rational.
D. Johnny is incorrect because a terminating decimal is rational.

41/17 as a decimal rounded to the nearest hundredth

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?

Which of the following is not a subset of {1,2,3}?
