Answer
Rational numbers are numbers that can be expressed in the form $\displaystyle \frac{a}{b}\\$ ,
where a and b are integers and b is not equal to 0, written $b\neq 0$.
In decimal form, the decimal part either terminates, or has a repeating block of digits.
Work Step by Step
The set of rational numbers is the set of all numbers that can be expressed in the
form $\displaystyle \frac{a}{b}$ , where a and b are integers and b is not equal to 0, written $b\neq 0$.
The integer a is called the numerator and the integer b is called the denominator.
All integers are rational numbers, because we can write the integer as fraction with dfenominator 1.
Any rational number can be expressed as a decimal.
The resulting decimal will either terminate (stop), or it will have a digit that repeats or a block of digits that
repeat.
