Explanation:

Question 1

A proportion is defined as an equation or statement that shows two ratios are equal. A ratio is just a comparison of two quantities. So the correct option is b.

A ratio is the comparison of two quantities of the same kind. A proportion is an equality of two ratios. So the correct option is a.

In a proportion (e.g., \(a:b = c:d\)), the outermost values (a and d) are called extremes. The innermost (b and c) are means. So the correct option is b.

Answer:

b. proportion
