MULTIPLICACIÓN Y DIVISIÓN CON NÚMEROS REALES

MULTIPLICACIÓN Y DIVISIÓN CON FRACCIONES

Para la multiplicación:

Se multiplica el numerador por numerador y el denominador por el denominador.

Para la división se realiza un producto cruzado:

El primer numerador por el segundo denominador será el numerador del resultado, y el primer denominador por el segundo numerador, será el denominador del resultado:

Para divisiones verticales:

El numero será el resultado de la multiplicación de los extremos

        El denominador será el resultado de la multiplicación de los internos

Es exactamente lo mismo que el producto cruzado, solo que lo acomodamos verticalmente.

Ejemplos de división de números reales:

LEYES DE LOS SIGNOS

La multiplicación y la división con números enteros se basa en las leyes de los signos.

-Signos iguales el resultado espositivo

-Signos diferentes el resultado es negativo

Ejemplos de las leyes de los signos:
