If b is the midpoint of ac and the length of ac is 23.8 what is the legength of ab

Hey there,

So explain and to illustrate (how  is the midpoint of  and the length of  is 23.8 what is the length of 

                                       A-----------------B----------------C

So,  in the problem here is to be considered the (Whole area of this line).  is the whole thing. 

So, what we do in this problem, we do . . .

23.8 ÷ 2 because we need to find what is , so we will find the one half of it, which in this illustration is to be considered 

23.8 ÷ 2 = 



Hope this helps.
