This document provides examples and explanations for adding and subtracting fractions. It begins by explaining how to add fractions that have the same or different denominators. When the denominators are the same, you add the numerators and keep the same denominator. When the denominators are different, you find a common denominator and then add the numerators keeping the denominator. For subtraction, it explains that you follow the same process as addition but subtract the numerators instead of adding them. The document then provides a series of fraction addition and subtraction problems to practice these skills. It asks the student to calculate the sums and differences, reducing fractions when possible.

1. Actividad Quinto
Suma y resta
Suma de fracciones.
Si dos fracciones tiene el mismo denominador, se suman los numeradores y se deja el mismo denominador.
Si la fracción resultado se puede simplificar, se simplifica.
Si las fracciones tienen distinto denominador se reducen a común denominador y se suman los
numeradores dejando el denominador. Finalmente, si es posible se simplifica.
Resta de fracciones.
Si dos fracciones tienen el mismo denominador, se restan los numeradores y se deja el mismo denominador.
Si la fracción resultado se puede simplificar, se simplifica.
Si las fracciones tienen distinto denominador se reducen a común denominador y se restan los numeradores
dejando el denominador. Finalmente, si es posible se simplifica.
