Simplification of Rational Numbers in Math

Simplification of Rational Numbers

• A rational number can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD).
• The GCD of two numbers can be found using the Euclidean algorithm.
• Simplification does not change the value of the rational number.
• Example: 6/8 can be simplified to 3/4 by dividing both numerator and denominator by their GCD, which is 2.

Real-world Applications of Rational Numbers

• Cooking and Recipes: Rational numbers are used to represent fractions of ingredients, allowing for easy scaling of recipes.
• Finance: Rational numbers are used to represent interest rates, investment returns, and currency exchange rates.
• Science and Engineering: Rational numbers are used to represent ratios and proportions in scientific and engineering applications, such as the ratio of a circle's circumference to its diameter (π).
• Music: Rational numbers are used to represent musical intervals and rhythms, allowing for the creation of harmonious and complex musical compositions.
• Geometry and Architecture: Rational numbers are used to represent proportions and ratios in geometric shapes and architectural designs, ensuring balance and harmony in structures.

Simplification of Rational Numbers

• Simplifying a rational number involves dividing both the numerator and denominator by their greatest common divisor (GCD) to reduce the fraction to its simplest form.
• The Euclidean algorithm is a method used to find the GCD of two numbers.
• Simplifying a rational number does not change its value, only its representation.
