Suppose you have two numbers x, y ∈ Q (that is, x and y are
rational numbers).
a) Use the formal definition of a rational number to express
each of x and y as the ratio of two integers. Remember, x and y
could be different numbers!
(b) Use your results from (a) to show that xy must also be a
rational number. Carefully justify your answer, showing how it
satisfies the formal definition of a rational number.
(2) Suppose...
