if you have a 5-L fish tank how many 250-mL containers how many containers can you fill

You can fill 20 containers with a 5-L fish tank.

To calculate this, simply convert the total volume of the fish tank from liters to milliliters:

5 L = 5000 mL

Then divide the total volume of the fish tank by the volume of each container:

5000 mL / 250 mL = 20 containers

So, you can fill 20 containers with a 5-L fish tank.
