Hannah says all integers are rational. Is Hannah correct?

Hannah is correct.

Step-by-step explanation:

A rational number is a number that can be written as the quotient of two integer numbers.

This means that if we have an integer a, and an integer b, then:

a/b is a rational number.

In the particular case where b = 1 we have:

a/1 = a

This means that a is also a rational number.

And a can be any integer, then we can conclude that all the integer numbers are also rational numbers.

So Hannah is correct.

a=9
