A student wrote a proof about the product of two rational numbers: 1. Let 3 = and let y = à, where a and c are defined to be integers, and b and d are nonzero
integers.
2. By substitution, ry =
3. By applying the closure property of integers and nonzero integers on multiplication, ac is an
integer and bd is a nonzero integer.
What conclusion can the student now make about the product ty?
