Hola! :3
Desarrollamos:
(80%)(200%)(30)=x
(80/100)(200/100)(30)=x
(4/5)(2)(30)=x
(4)(2)(30/5)=x
(4)(2)(6)=x
72=x
Espero haberte ayudado :D
80 × 200
---- ----- × 30
100 100
Simplificar 80 / 100 : 4 / 5
Dividir : 200 / 100 = 2
= 4 / 5 × 2 × 30
Convertir a fracción : 2 = 2 / 1
Convertir a fracción : 30 = 30 / 1
= 4 / 5 × 2 / 1 × 30 / 1
= 4 × 2 × 30 / 5 × 1 × 1
Aplicar la propiedad :
[tex]a \times 1 = a[/tex]
= 4 × 2 × 30 / 5
Dividir : 30 / 5 = 6
= 4 × 2 × 6
Multiplicar :
= 48
