    The Concept of Simplifying Fractions

    Understanding Fractions

    A fraction consists of two parts: the numerator (the top number) and the denominator (the bottom number). It represents a part-to-whole relationship, indicating how many equal parts of a whole are being considered. For example, in the fraction 3/4, 3 is the numerator, and 4 is the denominator, signifying that three out of four equal parts are being considered.

    Simplification of Fractions

    Simplifying a fraction involves reducing it to its simplest form by dividing both the numerator and denominator by their greatest common divisor (GCD). The GCD is the largest number that evenly divides both the numerator and denominator without leaving a remainder.

    Formulae for Simplifying Fractions

    The simplification of fractions can be achieved using the following formulae:

    Formula 1: Finding the Greatest Common Divisor (GCD)

    To simplify a fraction, we first need to find the GCD of the numerator and denominator. This can be calculated using the Euclidean algorithm:

    GCD(a, b) = GCD(b, a % b) # Where % represents the modulo operation

    Formula 2: Simplifying the Fraction

    Once we have the GCD, we can simplify the fraction by dividing both the numerator and denominator by it:

    Simplified numerator = Numerator / GCD Simplified denominator = Denominator / GCD

    Example Calculations

    Let’s illustrate the process of simplifying fractions with a few examples:

    Example 1: Simplifying 6/12

    1. Find the GCD of 6 and 12 using the Euclidean algorithm: GCD(6, 12) = GCD(12, 6) = GCD(6, 0) = 6
    2. Simplify the fraction by dividing both the numerator and denominator by the GCD: Simplified numerator = 6 / 6 = 1 Simplified denominator = 12 / 6 = 2

    So, 6/12 simplifies to 1/2.

    Example 2: Simplifying 15/30

    1. Find the GCD of 15 and 30 using the Euclidean algorithm: GCD(15, 30) = GCD(30, 15) = GCD(15, 0) = 15
    2. Simplify the fraction by dividing both the numerator and denominator by the GCD: Simplified numerator = 15 / 15 = 1 Simplified denominator = 30 / 15 = 2

    So, 15/30 simplifies to 1/2, which is the same as 6/12.
