x:y = 2:3 ....(1)

y:z = 4:7 .....(2)

for equating y in both equation, eq (1)×4 and eq (2) ×3

x:y = 8:12

y:z = 12:21


so, x:y:z = 8:12:21


Hope it helps

Hi dear ,

--------------------------------------------------------------------------

 Given,

 x : y = 2 : 3

x / y = 2 / 3

x = 2y / 3  

Now,

y : z = 4 : 7 

y / z = 4 / 7

7y = 4z

z = 7y / 4.

So,
     x : y : z = 2y / 3 : y : 7y / 4

                       8y : 12y : 21y
                 =  --------------------
                             12

                = 8y :12y : 21y

                = 8 : 12 : 21
