Ответ:
En un colegio que en total tiene 648 alumnos, las cinco novenas partes son varones, y las tres quintas partes de ellos practican algún deporte, y además, las tres octavas partes de las mujeres también practican algún deporte, la cantidad de mujeres es de 288 y de varones es de 360.
Explanation:
Datos:
Total de alumnos: 648
Total de varones: 5/9 del total
Varones practican deporte: 3/5 de los varones
Mujeres practican deporte: 3/8 de las mujeres.
El primer paso es calcular el total de varones, y para ello, multiplicamos el total por 5/9
648 x 5/9 = 3240/9 = 360 varones en el colegio
De estos varones, 3/5 practican deportes, así que: 360 x 3/5 = 1080/5 = 216 varones del colegio practican algún deporte
Para calcular el número de mujeres, restamos del total, el número de varones:
648 – 360 = 288 mujeres en el colegio
Las que practican algún deporte son 3/8, así que: 288 x 3/8 = 864/8 = 108 mujeres del colegio practican algún deporte
