[tex] \frac{ \frac{am}{1} }{2} = \frac{ \frac{bm}{1} }{3} = > am \times \frac{1}{2} = mb \times \frac{1}{3} [/tex]
[tex] \frac{1}{3} > \frac{1}{2} = > \frac{2}{6} > \frac{3}{6} [/tex]

2AM=3MB=k

AM+MB=AB<=>AM+MB=45

2AM=k=>AM=k/2

3MB=k=>MB=k/3

AM>MB

AM+MB=k/2+k/3=(3k+2k)6=5k/6

AM+MB=AB<=>5k/6=45=>5k=270=>k=54

AM=54/2=27 cm

MB=54/3=18 cm
