Answer 2

Answer:

25 : 30 : 36

Step-by-step explanation:

If x : y = 5 : 6 Then ,

$\frac{x}{y} = \frac{5}{6}$

If Y : Z = 15 : 18

$\frac{y}{z} = \frac{15}{18}$

Now Y is same in the equation .

So equate these .

Y = 6 , Y = 15 . Therefore LCM of 15 and 6 = 30 .

$\frac{x}{y} = \frac{5}{6} \times \frac{5}{5} = \frac{25}{30}$

$\frac{y}{z} = \frac{15}{18} \times \frac{2}{2} = \frac{30}{36}$

Therefore x : y : z = 25 : 30 : 36
