**Reiny**, Saturday, February 9, 2013 at 10:38pmmake a sketch on a number line of the given.

let BC = x

then AB = 25-x and CD = 46 -x

CD/AB = 5/2

(46-x)/(25-x) = 5/2

92 - 2x = 125-5x

3x = 33

x = 11

So BC = 11 cm

check:

then AB = 25-11= 14 and CD = 46-11 = 35

ration of CD/AB = 35/14 = 5/2
