If A : B = \(\frac{1}{3}\) : \(\frac{7}{12}\) , B : C = \(\frac{1}{2}\): \(\frac{5}{6}\) and C : D = \(\frac{3}{4}\) : \(\frac{5}{8}\) then A : B : C : D equal to:
Answer & explanation
Correct answer: option 3
A : B = \(\frac{1}{3}\) : \(\frac{7}{12}\) = 4 : 7
B : C = \(\frac{1}{2}\) : \(\frac{5}{6}\) = 3 : 5
C : D = \(\frac{3}{4}\) : \(\frac{5}{8}\) = 6 : 5
A : B : C : D
4 : 7
3 : 5
6 : 5
