Para resolver expresiones en las que se incluyen en sumas y restas de fracciones es necesario
seguir algunos pasos fundamentales:
:: Primero, si la expresi坦n tiene n炭meros mixtos, estos se deben transformar en fracciones impropias.
:: Segundo, se debe expresar cada fracci坦n con un com炭n denominador. Es decir, se debe
complificar cada fracci坦n para que queden con el mismo m鱈nimo com炭n m炭ltiplo de

:: Luego, se resuelve la suma o resta de fracciones teniendo en cuenta que cada numerador
conserva el mismo signo de la fracci坦n en que se encuentra.
:: Finalmente, se simplifica si es posible.
Si la expresi坦n tiene signos de agrupaci坦n, estos se deben eliminar y se resuelven las
