很简单啊,原来杯子里面是1/5的orange juice
后来杯子被加满,加入的是三种混合起来的果汁,橙汁占其中的1/3
最后橙汁的比例：
原来的1/5+ 后来加入的（1-1/5）* 1/3
=1/5+ 4/15
=7/15
一个量杯包含了一杯橙汁的1 / 5。，然后填写它是一种混合物，它包含等量的柑橘，柚子1杯大关，菠萝juices.w??hat最终混合物分数是橙汁
我只能翻译到这里但是不会算 就给了一个条件
对不起全是英语，看不懂。
翻译为汉语 一个量筒里盛有 1/5的橙汁，后来为了把这量筒盛满，又倒入了等量的橙汁 葡萄汁 苹果汁 问量筒里最后一共有多少橙汁 用分数表示
假设倒入了等量的橙汁 葡萄汁 苹果汁分别为x
则 1/5 +3x=1 求得x=4/15
量筒里最后一共有橙汁4/15+1/5=7/15...
