Study Notes
Rational Fractional Numbers
- A rational fractional number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
- Characteristics of rational numbers include being able to be expressed in decimal form, which either terminates or repeats.
Characteristics of Rational Fractional Numbers
- Not all numbers are rational; irrational numbers, such as π (pi) or √2, cannot be expressed as fractions of integers.
- A key characteristic is that they can always be represented as a fraction a/b, with integers a and b (b ≠0).
Examples of Rational Fractional Numbers
- Examples include numbers like 1/2, 3, -4/5, and 0.75, all of which can be expressed as fractions.
- The number 2 can be represented as 2/1, making it rational.
Classification of Rational Fractional Numbers
- Rational fractional numbers can be categorized into classes such as:
- Proper fractions: where the absolute value of the numerator is less than the absolute value of the denominator (e.g., 1/3).
- Improper fractions: where the numerator's absolute value is greater than or equal to that of the denominator (e.g., 5/2).
- Mixed numbers: which consist of a whole number and a proper fraction (e.g., 1 1/2).
Rational vs. Irrational Numbers
- Rational fractional numbers differ from irrational numbers in that they possess a precise fractional representation, while irrational numbers cannot be expressed as a simple fraction.
- Rational numbers form a subset of real numbers that exclude irrational numbers, highlighting the distinct boundaries between these categories.
