Adding and Subtracting Fractions with Equal Denominators

This page provides a detailed explanation of how to perform basic arithmetic operations with fractions that share the same denominator, emphasizing the suma y resta de numeradores en fracciones.

The content explains that when working with fractions that have the same denominator, we are essentially working with parts of the same whole. The process involves operating only with the numerators while maintaining the same denominator.

Definition: A fraction consists of two parts - the numerator (top number) and denominator (bottom number), where the denominator represents the whole, and the numerator indicates the parts we take from that whole.

Highlight: When adding or subtracting fractions with equal denominators, only the numerators are added or subtracted while the denominator remains unchanged.

Example: In the visual representation shown, fractions are illustrated with clear separation between numerator and denominator, demonstrating how they represent parts of a whole.

Vocabulary:

• Numerador (Numerator): The top number in a fraction
• Denominador (Denominator): The bottom number in a fraction
• Fracciones (Fractions): Numbers that represent parts of a whole

Quote: "Cuando sumamos y restamos fracciones con igual denominador, estamos sumando y restando partes de un mismo todo." (When we add and subtract fractions with equal denominators, we are adding and subtracting parts of the same whole.)
