Study Notes
Adición De Fracciones Con Igual Denominador
- Para sumar fracciones con igual denominador, se suman los numeradores y se mantiene el mismo denominador.
- Ejemplo: 1/4 + 2/4 = 3/4
- Se pueden sumar varias fracciones con igual denominador, sumando los numeradores y manteniendo el denominador.
Adición De Fracciones Con Distinto Denominador
- Para sumar fracciones con distinto denominador, se necesitan encontrar el mínimo común múltiplo (mcm) de los denominadores.
- Se convierten las fracciones al mismo denominador (mcm) y se suman los numeradores.
- Ejemplo: 1/4 + 1/6 = ?
- mcm de 4 y 6 es 12
- Convertimos las fracciones: 3/12 + 2/12 = 5/12
- Se pueden sumar varias fracciones con distinto denominador, encontrando el mcm y sumando los numeradores.
Representación Gráfica De Sumas De Fracciones
- Se puede representar gráficamente la suma de fracciones mediante rectángulos o áreas divididas.
- Cada fracción se representa como una parte de un todo, y la suma se representa como la unión de las partes.
- La representación gráfica ayuda a visualizar la suma y a comprender mejor el concepto.
Resta De Fracciones Con Igual Denominador
- Para restar fracciones con igual denominador, se restan los numeradores y se mantiene el mismo denominador.
- Ejemplo: 3/4 - 2/4 = 1/4
- Se pueden restar varias fracciones con igual denominador, restando los numeradores y manteniendo el denominador.
Resta De Fracciones Con Distinto Denominador
- Para restar fracciones con distinto denominador, se necesitan encontrar el mínimo común múltiplo (mcm) de los denominadores.
- Se convierten las fracciones al mismo denominador (mcm) y se restan los numeradores.
- Ejemplo: 3/4 - 2/6 = ?
- mcm de 4 y 6 es 12
- Convertimos las fracciones: 9/12 - 4/12 = 5/12
- Se pueden restar varias fracciones con distinto denominador, encontrando el mcm y restando los numeradores.
Adding Fractions with the Same Denominator
- To add fractions with the same denominator, add the numerators and keep the same denominator.
- Example: 1/4 + 2/4 = 3/4
- Multiple fractions with the same denominator can be added by adding the numerators and keeping the denominator.
Adding Fractions with Different Denominators
- To add fractions with different denominators, find the least common multiple (LCM) of the denominators.
- Convert the fractions to the same denominator (LCM) and add the numerators.
- Example: 1/4 + 1/6 = ?; LCM of 4 and 6 is 12
- Convert the fractions: 3/12 + 2/12 = 5/12
- Multiple fractions with different denominators can be added by finding the LCM and adding the numerators.
Graphical Representation of the Sum of Fractions
- The sum of fractions can be graphically represented using rectangles or divided areas.
- Each fraction is represented as a part of a whole, and the sum is represented as the union of the parts.
- The graphical representation helps visualize the sum and better understand the concept.
Subtracting Fractions with the Same Denominator
- To subtract fractions with the same denominator, subtract the numerators and keep the same denominator.
- Example: 3/4 - 2/4 = 1/4
- Multiple fractions with the same denominator can be subtracted by subtracting the numerators and keeping the denominator.
Subtracting Fractions with Different Denominators
- To subtract fractions with different denominators, find the least common multiple (LCM) of the denominators.
- Convert the fractions to the same denominator (LCM) and subtract the numerators.
- Example: 3/4 - 2/6 = ?; LCM of 4 and 6 is 12
- Convert the fractions: 9/12 - 4/12 = 5/12
- Multiple fractions with different denominators can be subtracted by finding the LCM and subtracting the numerators.
