Si se sembró 1/4 parte con soja el resto son 3/4  
La siembra de trigo en las 2/3 partes de 3/4 es operar 2/3 * 3/4 = 6/12 que simplificado es 1/2 (la mitad del campo)

1/2 de 900 hectáreas es 900 : 2= 450 hectáreas

Hola chuky40,

Datos:
-900 hectáreas (área del terreno)
- ¼ parte = soja
- ⅔ del resto = trigo

1) Se calcula la equivalencia de ¼ en hectáreas
900÷4 = 225
225x1 = 225 <--- Valor de ¼ de hectáreas

2) Se resta el valor de ¼ (225) para hallar el valor de las ⅔ equivalentes al trigo
900-225 = 675 <--- Espacio sobrante

3) Se calcula la equivalencia de ⅔ en hectáreas
675÷3 = 225
225x2 = 450 <--- Número de hectáreas donde se sembró el trigo

Rpta: Con 450 hectáreas se sembró el trigo
