Answer:
There are altogether 1670ml of water.
Step-by-step explanation:
First, you have to convert litre to mililitres by multiplying it by 1000 :
[tex]1l = 1000ml[/tex]
[tex]1l \times 1.4 = 1000ml \times 1.4[/tex]
[tex]1.4l = 1400ml[/tex]
Next, you have to add up both bottles together :
[tex]1st \: \: bottle = 1400ml[/tex]
[tex]2nd \: \: bottle = 270ml[/tex]
[tex]total = 1400 + 270 = 1670ml[/tex]
