题目是这样的:Different colored electrical wires are stored in two drawers. Only red wires, yellow wires, and black wires are stored in the first drawer. There are 22 red wires. Three-eighths of the wires in the drawer are yellow and 1/6 of the wires in the drawer are black. Only white wires are stored in the second drawer. One-fifth of all the wires in both drawers are white. What is the total number of yellow wires and white wires?
我做了好几遍,和结果都不一样,感觉也没理解错啊,希望哪位大侠帮忙解一下,要列上步骤啊

第一个抽屉总数:22÷(1-3/8-1/6)=48根
因此:黄线数量48*3/8=18根,黑线数量48*1/6=8根

白线的数量是总数量的1/5,则第一个抽屉里的电线数占总数的4/5
所以两个抽屉的总数是48÷4/5=60
白线为60*1/5=12根
