Error PLS-00905 y error PLS-00304

Me dá que lo que te falta es el pequeño detallito de la barrita de dividir, prueba esto.

Código SQL:

CREATE OR REPLACE PACKAGE paqueteboletin09
IS
FUNCTION multiplica(p_a IN NUMBER, p_b IN NUMBER)
RETURN NUMBER;
PROCEDURE tabla_multiplicar (p_x IN NUMBER, p_y IN NUMBER DEFAULT 10);
END paqueteboletin09;
/
 
CREATE OR REPLACE PACKAGE BODY paqueteboletin09 IS
FUNCTION multiplica(p_a IN NUMBER, p_b IN NUMBER)
RETURN NUMBER
IS
BEGIN
RETURN p_a * p_b;
END;
PROCEDURE tabla_multiplicar (p_x IN NUMBER, p_y IN NUMBER DEFAULT 10) IS
BEGIN
NULL;
END;
END paqueteboletin09;
