The answer is "proprtional".
set up a proportion and see if both sides simplify to the same answer. If the 2 ratios represent a constant ratio they will simplify into fractions
Area ratio = (edge-length ratio)2 Volume ratio = (edge-length ratio)3 Volume ratio = (area ratio)3/2
They have a constant rate or ratio.
A ratio is a comparison between two values. The values can be integers or fractions (ratios).
Direct variation.

The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.
Area ratio = (edge-length ratio)2 Volume ratio = (edge-length ratio)3 Volume ratio = (area ratio)3/2
A proportion is a statement that says "These two ratios are equal".
They have a constant rate or ratio.
It is a direct proportion.
For proportional relationships the ratio is a constant.
A linear relationship
A ratio is a comparison between two values. The values can be integers or fractions (ratios).
Direct variation.
If the ratio between each pair of values is the same then the relationship is proportional. If even one of the ratios is different then it is not proportional.
