6:8:9

Answer 2

Answer:

option (B) 6:8:9

Step-by-step explanation:

Firstly we had to make ratio of y equal in both the equation.

$\frac{x}{y} = \frac{3}{4} \\ \frac{x}{y} = \frac{3 \times 8}{4 \times 8} \\ \frac{x}{y} = \frac{24}{32}$

$\frac{y}{z} = \frac{8}{9} \\ \frac{y}{z} = \frac{8 \times 4}{9 \times 4} \\ \frac{y}{z} = \frac{32}{36}$

x:y:z = 24:32:36

= 6:8:9
