    6) D'un viatge de 540 km en Pere n'ha recorregut les 3/5 al matí i 1/4 al vespre. Quina fracció del camí li queda per recórrer?. Quants quilòmetres li falten per completar el viatge?.
    7) En Joan regala les 3/7 parts de les seves bales a en Gerard i encara li queden 42. Quantes bales tenia al principi?.
    8) Un ramader ven els 3/4 del nombre de caps de bestiar que té. Més tard els 3/4 de la resta, quedant així 16 caps de bestiar a la ramaderia. Quants animals tenia?
