. If a=2/3b , b=2/3c, and c=2/3d what part of d is b/

(a) 8/27 (b) 4/9 (c) 2/3 (d) 75% (e) 4/3

• a = 2b/3, b= 2c/3 , and c = 2d/3
  
  Then d = 3c/2
  
  But c = 3b/2
  
  Hence d = (3/2)*(3/2)b
  
  Then d = (9/4)b
  
  ==> b = (4/9)d
  
  In other words, 4/9 of d is b.

• ans is 4/9 c=2/3d
  now put c=2/3d in b=2/3c
  so b=2/3*2/3d
  b=4/9d
