Usando proporciones, hay que el mesmo costal dura 20 dias a un grupo de 15 gallinas y 12 dias a un grupo de 25 gallinas.
¿Qué es una proporción?
Una proporción es una fracción de la cantidad total, e puede ser encontrada aplicando una regla de três.
a 10 gallinas,un costal de alimentos les dura 30 dias. ¿cuanto dias les durara el mismo costal de alimentos a un grupo de 15 gallinas? La regla de três es dada por:
10 gallinas - 30 dias
15 gallinas - x dias
Las medidas son inversamente proporcionales, por eso, aplica-se multiplicación de linea:
15x = 300
x = 20
Para 25 gallinas:
10 gallinas - 30 dias
25 gallinas - x dias
25x = 300
x = 12
