Final answer:
To determine how much flour Alexi needs to make apple crumble for two people, we would need to know the original recipe proportions and scale it down accordingly. Without the specific apple crumble recipe, we can only speculate based on similar proportional scaling as seen in provided examples.
Step-by-step explanation:
If Alexi is making apple crumble for two people and needs to know how much flour to use, we would typically reference a recipe. However, from the information provided, there is a reference to pound cake where the ingredients are in equal pound measures.
The recipe for pound cake requires 1 pound of flour along with equal parts of other ingredients. Assuming the recipe for apple crumble requires similar proportions, if Alexi has ingredients in pound or gram measurements, she should use the same amount of each. However, if there's specific reference or context for apple crumble missing, we cannot determine the flour quantity without more information.
Nevertheless, considering proportional scaling as seen in the examples provided, if Alexi has a recipe for a certain number of servings, she would simply scale down the proportions to suit the number for two people.
As seen in the pancake example, ingredients are increased proportionally, a concept that applies to reducing as well. To determine the exact amount of flour, Alexi would need the original recipe and then scale it down accordingly.
Your complete question is: If Alexi makes apple crumble for two people, how much flour does she need?
