2.The ratio of apples to oranges in a lorry was 5:2,there were 248 oranges,how many apples were there?

1120g.
620个。

1.一个蛋糕的70%是面粉,20%是鸡蛋,剩下的成分是牛奶。如果使用的鸡蛋重320克,那么使用了多少面粉呢? 1120g.
2.一辆卡车上苹果与桔子的比例是5:2 ,现有桔子248个,问有多少个苹果?620个。

1)一个蛋糕的70%是面粉,20%是鸡蛋,剩下部分是牛奶.如果使用了鸡蛋320克,那么使用了多少面粉?
320÷0.2×0.7=1120,so 1120g flour was used.
2) 一辆卡车上苹果与桔子的比例是5:2 ,车上有248个桔子,问有多少个苹果?
Suppose there were x apples
5/2=x/248,x=620
so 620 apples were there.
