Explanation:

A number that can be made by dividing two integers (an integer is a number with no fractional part).

The word comes from "ratio".

Examples:

• 1/2 is a rational number (1 divided by 2, or the ratio of 1 to 2)

• 0.75 is a rational number (3/4)

• 1 is a rational number (1/1)

• 2 is a rational number (2/1)

• 2.12 is a rational number (212/100)

• −6.6 is a rational number (−66/10)

• etc

But π (pi) is not a rational number, it is an "Irrational Number".

Answer 2
