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".
