George wants to make a cake. The recipe requires 150 g each
of flour, sugar and butter, and 3 eggs. George only has 2 eggs
so he decides to make a smaller cake with the same proportions.

a) How much flour will George need to use?

b) If each egg weighs 25 g, how much will the cake weigh before it goes in the oven?

c) What fraction of the uncooked weight is flour? Simplify your answer.

d) If the cake loses 1/7 of its weight during baking (due to moisture loss), what will it weigh after baking?
