Apples to Apples - Remember when dealing with different units to always change them to the same unit:

For example: Which is cheaper?

Bag A - 6 kg for $2.00 or Bag B - 3600 g for $2.40

Bag A - Change 6 kg to 6 000 g or 6 000 g for $2

Next, 6 000 g divided by $2.00 = 3000

So, Bag A is 3 000 g per $1.00

B - 3 600 g divided by $ 2.40 = 1 500

So, Bag B is 1 500 g per $1.00

So, Bag A is cheaper as it gives you 3 000 g per dollar, while Bag B only gives you 1 500 g per dollar.
