A baker has 6 kg of flour to make some cakes. He needs 225 g of flour to make each cake.If he makes 12 cakes, how much flour does he have left?

To find out how much flour the baker has left, we first calculate the total amount of flour used to make 12 cakes: 225g/cake * 12 cakes = 2700g. Since 1kg = 1000g, the total amount of flour used is 2700g / 1000g/kg = 2.7kg. Subtracting this from the initial amount of flour (6kg - 2.7kg) gives us the amount of flour left, which is 3.3kg.
