Rational Number
Any number that can be made by dividing one integer by another. 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)

But Pi is not a rational number, it is an "Irrational Number".
