Respuesta:
El número será 3000
Explicación paso a paso:
Numero = x
Primer porcentaje = (50%)*x = (50/100)*x = (1/2)*x
Segundo porcentaje = (35%)*x = (35/100)*x = (7/20)*x
Planteamos:
Primer porcentaje - Segundo porcentaje = 450
(1/2)*x - (7/20)*x = 450
(10/20)*x - (7/20)*x = 450
((10-7)/20)*x = 450
(3/20)*x = 450
x = 450*(20/3)
x = 3000
