9/20
You need to have the same denominator so multiply it by 5 on the bottom and top to get 5/20 then you can compare it 5/20 < 9/20
I'm pretty sure the answer is 4 because, 4*21= 84.

Answer:
XZ = 2.5 BD
Step-by-step explanation:
Comparing the two triangles,
= 
= 
⇒ XZ = 
= 15
XZ = 15
So that,
BD:XZ = 6:15
= 1:2.5
Therefore, the relationship between BD and XZ is XZ = 2.5 BD.
