a:b=1:2
b:c=3:4
a : b : c
1 : 2
3 : 4
so b= 2×3=6
a:b=1:2
a=(1/2)×6=3
b:c=3:4
c=(4/3)×6=8
a:b:c=3:6:8

The value of a : b : c  = 3 : 6 : 8

Step-by-step explanation:

We have,

a : b = 1 : 2                                    ........(1)

and  b : c = 3 : 4                           ........(2)

To find, the value of a:b:c  =?

Multiplying equation (1) by \dfrac{3}{2}, we get

a:b=1\times \dfrac{3}{2}:2\times \dfrac{3}{2}

a:b=\dfrac{3}{2}:3     ........(3)

Comparing equations (2) and (3), we get

a:b:c=\dfrac{3}{2}:3:4

Mutiplying by 2, we get

a : b : c = 3 : 6 : 8

Hence, the value of a : b : c  = 3 : 6 : 8
