280.【carolnan】讲60以内除了1之外的正的约数中,除了1和本身不包含与60相同的约数的个数,我算的是15 什么意思?
291.V1【Brooke112】PS。。。 Half of the number K is decreased by 10%k, and then the result is divided by 4. The final result is 180. What is k? 我确定没记错!!我耗了好多时间。。。。 答案里面有1600,1800,2250,14400,还有一个记不住了。。。。但是。。。。我不知道答案。。。算了好久= = 麻烦死了 V2【sarah111111】有一道题是说一个数字 K, the half of k reduces by 10%, the result divided 4 is 180,what is the value of k??
V3【ashuracy】50%的神马deceased by10%的神马除以4是180,鸡精上算得是1200,我算得是1800,720除以0.4即可
感觉求出来是1600.不是V3的那种算法》?~?~求NN解答~~谢谢
