Jodie buys 12 cans of cola. There are 330 ml of cola in each can. Rob buys 4 bottles of cola. There is 1 litre of cola in each bottle. Rob buys more cola than Jodie. How much more?
The answer is: (4X1000)-(12X330)= 40, ao 40 ml more. You may wonder why 1 litre is 1000, as 1 litre of cola= 1000 ml of cola so we have to convert 1 L to 1000ml in the anwer. Rob buys more cola than Jodie means they are asking the differences of their cola volume, therefore, it is the cola that Rob has minus the cola that Jodie has.
