I don't remember ever doing problems like this in school but I think the answer is 6:15:8.
Since there's an X in each ratio I found the LCM of each X (2 and 3) which is 6 and then multiplied the other number by whatever I had to multiply X by to get 6.
X:Y = 2:5 = 2 * 3:5 * 3 = 6:15
X:Z = 3:4 = 3 * 2:4 * 2 = 6:8
X:Y:Z = 6:15:8
Only by making X the same number in each ratio do Y and Z then become comparable to each other.
Does that make sense?

The similar question has been answered already.
X : Y = 2 : 5
X : Z = 3 : 4
LCM of 2 and 3 is 6
X : Y = 6 : 15
X : Z = 6 : 8
X : Y : Z = 6 : 15 : 8

x:y=6:15 multiply by 3
y:z=15:20 multiply by 5
x:y:z=6:15:20
