Answer 1

Step-by-step explanation:

1.In other words, any integer a can be written as a = a/1, which is a rational number. Thus, every integer is a rational number. Clearly, 3/2,-5/3, etc. are rational numbers but they are not integers. Hence, every integer is a rational number but a rational number need not be an integer.
