Hello.
One jug contains
650 millilitres of water.
The other jug contains
300 millilitres of oil.
In order to find how much more water there is than oil, we need to take the amount of oil and subtract it from the amount of water:
[tex]\mathrm{650-300}[/tex]
[tex]\mathrm{350}[/tex]
Therefore, there are 350 more millilitres of water than oil.
I hope it helps.
Have a nice day.
