**Answer:**</h2>

Zoe's Fish tank holds 27 L of water, so this is the capacity of the tank. On the other hand, Zoe uses a 3L container in order to fill the tank, so the question is how many times does she have to fill the three litter container in order to fill the fish tank? Let's solve this as follows:

**First time: **

She pours **3L**

**Second time: **

She pours another **3L, **but she previously poured **3L, **so she has poured **6L**

**Third time: **

She pours another **3L, **but she previously poured **6L, **so she has poured** 9L**

**Fourth time: **

She pours another **3L, **but she previously poured **9L, **so she has poured **12L**

**Fifth time: **

She pours another **3L, **but she previously poured **12L, **so she has poured **15L**

**Sixth time: **

She pours another **3L, **but she previously poured **15L, **so she has poured **18L**

**Seventh time: **

She pours another **3L, **but she previously poured **18L, **so she has poured **21L**

**Eighth time: **

She pours another **3L, **but she previously poured **21L, **so she has poured **24L**

**Ninth time: **

She pours another **3L, **but she previously poured **24L, **so she has poured **27L**

<em>According to this, she needs to pours the </em><em>**3L **</em><em>container nine times in order to fill the fish tank. This can also be solved dividing </em><em>**27L/3L= 9**</em>
