If the length of the segment AB is 1,M is the midpoint of the segment AB,and point C divides the segment MB into two parts such that MC:CB=1:2,then the length of AC is

英语翻译If the length of the segment AB is 1,M is the midpoint of the segment AB,and point C divides the segment MB into two parts such that MC:CB=1:2,then the length of AC is
如果一线段AB的长度为1,M是该线段AB的重点,C把线段MB分成两部分,其中MC：CB=1:2,那么线段AC长是多少?
MC：CB=1:2 => BC=2/3 *MB
MB=1/2 *AC=1/2 => BC=1/3
AC=AB-BC=1-1/3=2/3

如果AB段的长度是1，M是AB段的中点，点C把段MB分成两段，且MC:CB=1:2,,求AC的长度

直线AB长1，M是直线AB的中点，C分直线MB成比例MC:CB=1:2，求AC长？
AB=1，AM=MB
所以AM=MB=1/2
又由MC:CB=1:2
得MC=1/6
所以AC=2/3

线段AB的长度为1，M是线段AB的中点，点C把线段MB分成两段，其中MC:CB=1:2，求线段AC的长.

问题翻译: 如果线段AB长度为1,M是线段AB的中点. 点C把MB分为两部分,且MC:MB=1:2 求AC长多少?
问题解答:
∵M平分线段AB,且AB长为1
∴AM=MB=1 ÷ 2=0.5
∵MC:MB=1:2
∴MC=0.5×1/3(三分之一)=1/6(六分之一)
∵AC=AM=MC
∴AC=1/2+1/6=2/3(三分之二)

如果线段AB长1，M是AB的中点，C是MB上的一点，其中MC：CB=1:2, 问AC多长？
MB=1/2AB=0.5
MC+BC=MB=0.5
又因为MC:CB=1:2 ...

已知AB=1， M是 AB的中点，点C把MB分成两份，MC:CB=1:2.则AC长多少？
∵M平分线段AB,且AB长为1
∴AM=MB=1 ÷ 2=0.5
∵MC:MB=1:2
∴MC=0.5×1/3(三分之一)=1/6(六分之一)
∵AC=AM=MC
∴AC=1/2+1/6=2/3(三分之二)
