Let’s say you only have ½ a box of brownie mix (260 g). One full box of brownie mix has 520 grams. If you were to make a whole box of brownie you would need 3 tablespoons of water, ½ cup oil and 2 eggs. Since you only have ½ a box you need to change these amounts. How much water, oil and eggs will you use to make the ½ box of brownies?
