Answer: ella usó (1/2) kg de arroz para cocinar.
Step-by-step explanation:
La madre de Ernesto tenía una bolsa con 3/4 kg de arroz.
Sabemos que uso 2/3 de esa cantidad para hacer un guiso.
Entonces ella usó 2/3 de 3/4 kilogramos de arroz.
Entonces ella usó:
(2/3)*(3/4) kg de arroz.
Recordemos que esto se puede escribir como el producto entre los numeradores dividido por el producto de los denominadores:
(2*3)/(3*4) kg de arroz.
(6/12) kg de arroz
(1/2) kg de arroz.
Esto significa que ella usó (1/2) kg de arroz para cocinar.
