Answer:
1 : 8
Step-by-step explanation:
For similar figures with ratio of sides = a : b
Then ratio of areas = a² : b² and
ratio of volumes = a³ : b³
Given ratio of areas = 1 : 4
linear ratio = 
: 
= 1 : 2
ratio of volumes = 1³ : 2³ = 1 : 8

Answer:
x=-4/5
Step-by-step explanation:
8/20=x/-2
simplify 8/20 into 2/5
