Can anyone help with this maths question please. It takes 2 dogs 18 days to eat some tinned dog food, how long would it take 3 dogs to eat the same amount of food?
My ds has worked it out but I'm still puzzled. The answer is 12.
Please breakdown working out for me. I have tried doing it using equation method but not much luck.
