Fracciones: sumar y restar

by Diego Ronaldo Cela Montero
1

Para restar fracciones con denominadores diferentes, se busca un común denominador.

2

Al restar fracciones, el signo del resultado depende de los valores de los numeradores.

3

Se pueden sumar fracciones con diferentes denominadores sin buscar común denominador.

4

Si las fracciones tienen el mismo denominador, se pueden restar directamente los numeradores.

5

Para sumar fracciones, se deben convertir a un mismo denominador.

6

Si el resultado es una fracción impropia, se convierte automática y siempre a número mixto.

7

Al sumar, se deben restar los numeradores.

8

Siempre se deben reducir fracciones antes de sumar o restar.

9

Se restan los denominadores y se dejan los numeradores igual.

10

Al sumar fracciones, se suman los numeradores y se mantiene el denominador.
