Malik's recipe for 4 servings of a certain dish requires 1.5 cups of pasta. According to this recipe, what is the number of cups of pasta that Malik will use the next time he prepares this dish?
(1) The next time he prepares this dish, Malik will make half as many servings as he did the last time he prepared the dish.
(2) Malik used 6 cups of pasta the last time he prepared this dish.
请教各位NN,
关于题目理解:
Malik's recipe for 4 servings of a certain dish requires 1.5 cups of pasta.
一开始没看懂这句话的意思,请NN告知这句话的具体含义?谢谢。
我猜测这句话的意思是否说:
Malik的食谱:
一顿菜的4 servings(实在不是很清楚这句的意思)需要1.5 杯的pasta,
也就是告诉了一个比例:
S=4:1.5
题目问:下次需要多少杯的pasta
条件1:下次Malik做的servings是上次的一半;
但题目是没有告诉上次servings是多少,因此无法求出。
条件2:上次用了6杯pasta
按照题目里已知的比例:
S=4:1.5,可以求出上次的Servings=16,
再结合条件1:下次Malik做的servings是上次的一半,可以求出下次的Servings=16/2=8
因此选C
