Answer 1

Answer: Third option.

Step-by-step explanation:

In order to solve the given exercise it is important to remember that:

1. Rational numbers are defined as those numbers that can be wrriten as a  simple fraction.

2. The symbol for Rational numbers is: Q

3. Integers can be positive numbers, negative numbers and zero.

4. The symbol for Integers is: Z

5. Fractions have the following form:

$\frac{a}{b}$

Where:

 "a" is the numerator and "b" is the denominator.

The numerator "a" and the denominator "b" are both Integers ( and $b\neq 0$)

Therefore, based on the information given above, you can conclude that Rational numbers are numbers of the form $\{\frac{a}{b}|a,b$ ∈ $Z,b\neq0\}$
