On a number line, the coordinates of P and Q are 8 and 48, respectively. The midpoint of PQ (which is a repeating decimal) is B, the midpoint of BQ is C, and the midpoint of PC (which is a repeating decimal) is D. What is the coordinate of D?

HAHAHA!!!!....that's a lot of midpoints   !!!!

 

Midpoint of  PQ  =  (8  + 48) / 2  =  56/2  = 28  =  B

 

So  midpoint of   BQ   =  ( 28   + 48)/ 2  =  76/ 2  =  38  =  C

 

And midpoint  of PC  =  (8 + 38) / 2  =   46/ 2   =  23   =  D 

 

 

 

cool cool cool
