Respuesta :

3. Because each container holds one third.

Amount of water hold by each identical container =[tex] \frac{1}{3} [/tex] of a liter

Amount of water hold by each identical container =[tex] \frac{1}{3} \times 1 [/tex] liter

= [tex] \frac{1}{3} [/tex] liter

Let 'n' be the number of containers that hold 1 liter of water.

According to the question,

[tex] \frac{1}{3} \times n =1 [/tex]

n =[tex] 3 \times 1 [/tex]

n =3

So, 3 containers are needed to hold 1 liter of water.
