a/b=4/5, b/c=5/6, d=7, d/e=2/3, e/f=1/4. Find abc/def..?

• a/b = 4/5
  b/c = 5/6
  d = 7
  d/e = 7/3
  e/f = 1/4 Find abc/def...?
  
  Solution should be in a descriptive form.

• a/b = 4/5
  ===> a:b = 4:5
  b/c = 5/6
  ===> b:c = 5:6
  So,
  a:b:c = 4:5:6
  Let a = 4x
  then b = 5x
  and c = 6x
  
  d = 7
  d/e = 7/3
  e = 3/7*d
  =3/7*7
  =3
  
  e/f = 1/4
  f = 4*e
  =4*3
  =12
  
  abc/def = 4x*5x*6x/(7*3*12)
  =10*x^3/21
