7分钟内给高分,守信.1.一个数分别除以1又1/5,3/10,4/15,所得商均为整数,这个数最小是几?2.已知a：b=

能,200*0.6*0.56+200*0.4*0.28=89.6 ,200*0.53=106 明显前面的钱少于后面的,话说这个很简单,

15和12的最小公倍数是3
所以正方形小纸片的边长最大是3厘米

I am going to do many things and be very busy in staurday.So I do my homework on Saturday morning.
In the afternoon,I am going to do housework with my mother.Because I am a good girl,I am helpful at home.In the evening ,I am going to visit my grandparents with my parents and we are going to the park together.Because there is a kite show.And my grandparents likes making kites.
I think,we can see many beautiful kites there.And we are going to buy some beautiful kites,too.
This is my happy staurday.I.What about your weekend?Can you tell me?

设第一袋x,
3x/5 =114/2
x = 95
114-95=19
8/15:8/12 =4:5
18/25:21/25 = 6:7
(16x/3+0.25x)/(5/9)=(5*35+26)/35
16x/3+0.25/x=5*(5*35+26)/(35*9)
64x+3x=5*(5*35+26)*12/(35*9)
67x=67x4/7
x=4/7

首先,设7分钟练习量为X,那么小刚完成量为X并加上16% 就等于X*116% 小贾为X*1.25 小磊为X/12*11 那么我们假设X为200 那么小刚完成量等于：200*116%=232 小贾完成量等于：200*1.25=250 小磊完成量等于把指定200,分成12份,他完成了其中的11份 等于200/12*11=183.333333333 约等于184 所以,小刚和小贾都合格了 小磊没有合格 完成最多的是小贾 250个

B

（500+200+500+200）/7=200米

On October 13th 2011,2 year old Yue-yue (real name Yue Wang) was hit down by two cars,one after another,at Foshan Nanhai Huangqiguangfo Wujin city.In 7 minutes,18 people passed by,but none went forward to help.Finally,it was a trash picking lady Xian-mei Chen who stepped up to help,and this led to widespread discussion on the internet.On October 21st 2011,Yue-yue died slightly after midnight at 00.32 after days of attemped rescue at the hospital.
The moral of giving those who fall a helping hand.An old man falls at the roadside,many people come around and look,but no one steps forward to help,how much sadness and anger does this picture bring.What is it that makes those passerbys so cold,so unmoved?I think there are two main reasons.Firstly,as our nation's laws are not sufficiently comprehensive,they are afraid to become the next "Peng Yu",saving someone only to be framed.But more importantly,we have to admit that our citizens' morality is going down consistently.We need to solve this problem immediately.Firstly,the nation should pass the related laws,to punish those who do not help,and reward those who do.Use the law to recall the people's conscience,and prevent heros from shedding blood,and tears.Secondly,we should improve our moral and civic education for the citizens,to promote the traditional Chinese morals.Only when our morality has gone up,can our nation finally become a harmonious China.
我虽然不能保证我的答案是没有错误的,但前面几位的答案语法以及文法的错误的多只显示他们对于翻译软件的依赖,对于这个,我是无法容忍的.
