/etc/nginx/nginx.conf.六年级附加题:甲数和乙数的比是2:3.乙数和丙数的比是4:5.甲数和丙数的比是多少?
六年级附加题:甲数和乙数的比是2:3.乙数和丙数的比是4:5.甲数和丙数的比是多少?小学六年级数学形成性测试卷(三)上册的第四·五单元测试卷的附加题.各位学姐学长帮帮学妹吧~~~
甲数和乙数是三分之二,乙数和丙数是五分之四,把这俩分数通分它们的最小公倍数.等于十五分之十和十五分之十二,再相除,等于10:12=5:6.所以,甲数和丙数的最简整数比是5:6.
与《六年级附加题:甲数和乙数的比是2:3.乙数和丙数的比是4:5.甲数和丙数的比是多少?》相关的作业问题
中高年级教师捐款总数占全校捐款的1-10/33=23/33,中高年间捐款比试12:11,12+11=23,说明中年级老师捐款占全校的12/33,高年级的占11/33,他们之间相减等于1/33,就是400元,所以全校一共捐款400*33=13200元
甲是乙的8/9
设未知数吧设总数为x1/9*x+7=1/6*xx=14额,明白吗
选择2方案,由三角形俩边之和大于第三边可以看出2方案最短
(1)99× —(有简便算法就用简便算法) 98 5 99x97/98=(98+1)x97/98=98x97/98+97/98=97+97/98=97又97/98(2)甲乙两数的比是3:4,乙数减甲数得 5/14,求乙数.(5/14)/(4-3)=5/14乙是:(5/14)*4=10/7
甲单干需4/1/4=16天合作须1/(1/16+1/18)=144/17天甲比乙多做了这项工程的(1/16-1/18)*144/17/1=1/17
不对,六年级没有负数,但当甲等于0时,依然错误.
设月份为x则:2(50+5x)=88+12x.解得x=6.所以是六个月
甲25KM/h乙20KM/h提示:由题意可知,全程180KM.甲乙五小时一共走了180+45=225KM,即甲乙速度之和为45KM/H.所以第一次相遇为出发后四小时甲九小时一共走了180+45=225KM,乙九小时一共走了180千米,所以甲乙速度易求得自己动手算,一个一个字打出来,虽然没分,也算是怀念小学生活吧…
1.一楼的已经做了2.设乙的速度为x m/s.3*60=180(秒)200*6-(40*6+40x)=200xx=4(40*6+40*4)/3就能得出直径3.设这批苹果为单位1,甲等苹果每千克应卖多少X元.0.7(7÷12)+X(5÷12)-0.8=0.8×25%4.设两城相距x千米.(x-200)/(x/10)=20
甲、乙合作要6天完成所以三人合作要1÷(1/6+1/12)=4天完成
甲乙两车共运一堆煤,运完时,甲车运了总数的7/15多12吨,比乙车多运1/2,甲车运了多少吨?乙车运总数的(7/15)/(1+1/2)多12/(1+1/2)即14/45多8吨 总数:(12+8)/(1-7/15-14/45)=90吨 甲90*7/15+12=54吨
8+x/15+x=9/10(8+x)x10=(15+x)x9解得x=55

1.45+15×6=2.250÷5×8= 3.6×5÷2×4= 4.30×3+8=5.400÷4+20×5= 6.10+12÷3+20=7.(80÷20+80)÷4=8.70+(100-10×5)=9.360÷40= 10.40×20=11.80-25= 12.70+45=13.90×2= 14.16×6=15.300
1.数学考查范围:重点中学摸底考试的数学题还是以奥数题为主,少部分小学数学题,也有部分学校考察少量初中数学的知识。难度有可能会有所提高,因为水涨船高,学生总体能力有所增强;而且还有一个问题,就是重点中学实验班招生规模小,这样摸底考试在全面了解学生水平和能力上,将面临着承担起在普通班中选优的更大重任。 2.英语考试范围、
