Understanding Fractions: Types and Operations

Study Notes

Fractions

A fraction is a way of representing a part of a whole or a part of a set. It consists of two main components: the numerator and the denominator. The numerator is the top number and represents the number of equal parts, while the denominator is the bottom number and represents the total number of parts.

Types of Fractions

There are three main types of fractions: proper fractions, improper fractions, and mixed fractions.

Proper Fractions: These are fractions where the numerator is less than the denominator. In other words, the value of a proper fraction is always less than 1.
Improper Fractions: These are fractions where the numerator is greater than or equal to the denominator. Improper fractions can be converted to mixed numbers by dividing the denominator of the improper fraction by the numerator, creating a whole number and a proper fraction.
Mixed Fractions: These are fractions that consist of a whole number and a proper fraction. The whole number represents the number of equal parts, and the proper fraction represents the remaining parts.

Fraction Operations

There are four basic operations with fractions: addition, subtraction, multiplication, and division.

Addition and Subtraction: To add or subtract fractions, the denominators must be the same. If they are not, you must find the least common multiple (LCM) of the denominators and convert the fractions to equivalent fractions with the same denominator.
Multiplication: To multiply fractions, you multiply the numerators and then the denominators. The resulting fraction represents the product of the original fractions.
Division: Dividing fractions is the same as multiplying fractions by the reciprocal of the divisor.

Fraction Equivalence

Two fractions are equivalent if they represent the same value. This means that they have the same fraction value, regardless of the specific numbers used in the fraction.

Fraction Addends

A fraction addend is a fraction that is being added or subtracted in a fraction addition or subtraction problem.

Fraction Addends as Dividends

A fraction addend as dividend is a fraction that is being divided in a fraction division problem.

Fraction Addends as Dividends with the Same Denominators

Fraction addends as dividends with the same denominators are fractions that are being divided in a fraction division problem, and they have the same denominator.

Fractions with the Same Denominators

Fractions with the same denominators are fractions that have the same denominator.
