data sufficient的题目
问题是what's the ratio of the number of cups of flour to the number of cups of sugar required in a certain cake recipe
为什么条件3/2 more cups of flour than cups of sugar are required in the recipe 这个条件是不充分的,因为我怕自己理解有误,所以最好能帮忙翻译下这句话的意思,然后再说原因,

问蛋糕菜谱里 面粉(杯)与 糖 (杯)的比例
这个条件是面粉比糖多1.5杯 x=y+1.5 无法单独求解x或y
