if a/b = c/d = d/e = 14/17.what is the value of (4a+5c+7d)/(4b+5d+7c)?

• first question will be find value of(4a+5c+7d)/(4b+5d+7e)?
  
  solution=
  a=14b/17
  c=14d/17
  d=14e/17
  
  now put value of a,b,d
  (4*14b/17+5*14d/17+7*14e/17)/(4b+5d+7e)
  take 14/17 commom from numerator
  so,
  14/17[(4b+5d+7e)/(4b+5d+7e)]
  so ans is 14/17

• Ans: 14/17
  sol: a=14b/17,c=14d/17,d=14e/17
  4(14b/17)+5(14d/17)+7(14e/17)/(4b+5b+7c)
  (14/17)(4b+5b+7d)/(4b+5b+7c)
  14/17
