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

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