Hi

Let x represent Jenny's portion

Jenny: x  

Demi: x/2

Drew: (3/4)x

Question states***

  x + x/2 + 3x/4 = 18in  |Multiplying thru by 4 so as all denominators=1

Solving for x

 4x + 2x + 3x = 72

        9x = 72

         x = 8in

Jenny: 8in  

Demi:  4in

Drew:  6in      |Note: portions total 18in
