PORCENTAJES... Un ciclista ha recorrido 18 km de una etapa que tiene 150 km en total. ¿Qué porcentaje le queda por recorrer? ... 18 de 150 => 1.800/150 = 12% ha recorrido ... 100–12 = 88% queda por recorrer. Una magdalena contiene 24 gramos de harina, que representan el 40% de su peso total. ¿Cuánto pesará una bolsa con una docena? ... 40% de P = 24 g => P = 2.400/40 = 60 g pesa cada una. ... 60 x 12 = 720 g pesará una docena. Queremos comprar unos pantalones que tienen un 20% de descuento. Si su precio final después de la rebaja es 27,2 €, ¿cuánto costaban los pantalones antes de ser rebajados? ... Ha pagado el 80%. => 27,2x100/80 = 34 € ers su precio inicial. Una panadería ha vendido 340 barras de pan de las 500 barras que habían preparado. ¿Qué porcentaje se ha vendido? ¿Qué porcentaje ha quedado sin vender? ... 340 de 500 => 340x100/500 = 68% ha vendido. ... 100 – 68 = 32% sin vender. Este año pagamos 252 € de IBI tras una subida del 5%. ¿Cuánto pagamos el año pasado, antes de la subida? ... El 105% de P = 254,6 => 252x100/105 = 240 € el año pasado.
