No but the equal ratios are called Equivalent Ratios.
Each side is equal to 1/2.
3:1, 6:2, 9:3
Yes the ratios are sometimes equal to each other.
Multiply each part of the ratio by the same number.
No; each ratio has to be the same for a direct variation.
No but the equal ratios are called Equivalent Ratios.

The answer will depend on what the ratios are. But since you have not bothered to provide that information, I cannot provide a sensible answer.
To determine which set of ratios are equivalent, we can simplify each pair of numbers. The ratio of 36 to 918 simplifies to 1:25.5, while 47 to 48 simplifies to approximately 0.979. The ratio of 12 to 34 is approximately 0.353, and 216 to 116 simplifies to approximately 1.862. None of the ratios are equivalent to each other.
similarity ratios are ratios in which both the ratios are equal to each other

Yes the ratios are sometimes equal to each other.
Multiply the antecedent of each ratio by the consequent of the other. If the products are equal, the ratios are equivalent.For example, given the two ratios A:B and C:D, if the product of A and D equals the product of B and C, then A:B::C:D (A is to B as C is to D).Two ratios a:b and c:d are equivalent if the crossproducts are the same.That is a/b = c/d if and only if a*d = b*c.
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.
