Answer 2

Answer:

Step-by-step explanation:

A   :   B    ,   B   :   C  ,     C   :   D

3        4       5        4       8       9

first we need to find lcm of both the B's  i.e 20

so A*5 and C *4

A   :   B    ,   B   :   C     ,  C   :   D

15     20     20     16       8       9

now we need to find lcm of both C's  i.e 16

so D*2

A   :   B    ,   B   :   C   ,    C   :   D

15     20     20     16      16      18

A:D=15:18

     = 3:6

     =1:2
