## Rational Numbers

Rational number: A number that can be expressed as the quotient of two integers, where the divisor is not zero. For example, 0.75, 3/4, and -2 are rational numbers.

A number that can be expressed as a/b, where a and b are integers and b= zero, examples include -4, 3.5, -1/2, and zero

A number that can be expressed as a/b, where a and b are integers and b= zero, examples include -4, 3.5, -1/2, and zero

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)

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)

1.5 is a rational number because 1.5 = 3/2 (it can be written as a fraction)

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.

- The number 8 is a rational number because it can be written as the fraction 8/1.
- Likewise, 3/4 is a rational number because it can be written as a fraction.
- Even a big, clunky fraction like 7,324,908/56,003,492 is rational, simply because it can be written as a fraction.
