Louise is baking cakes for a gathering. She needs 60 cakes in total, and has already produced half this many. Today, she calculates how many cakes she has left to make and bakes half this amount. The next day, she again calculates how many cakes she has left to make and bakes a third of this amount. How many more cakes does Louise need to bake? Give me reasons, before answering the question
Louise has already produced 60 cakes / 2 = 30 cakes. After calculating how many cakes are left, she bakes another 30 cakes / 2 = 15 cakes. The next day, she calculates again then bakes another 15 cakes / 3 = 5 cakes. She therefore still needs to bake 60 30 15 5 = 10 cakes. So the final answer is 10.
