Answer:

A ratio is a comparison of two or more numbers that indicate their relative sizes. Candidates may have some ideas about ratio but the concept of Compound Ratio may be completely new to them. When two or more ratio are multiplied, the resulting ratio is called a compound ratio. The first quantity of the ratios is called the antecedent and the second quantity is called the consequent.

For example, for two ratios, a:b m:n, the resulting ratio of compounds is am:bn. Examples of Compound Ratio include Duplicate Ratio and Triplicate Ratio. A compound ratio with two equal ratios is called a duplicate ratio. A compound ratio with three equal ratios is called a triple ratios. Let's explore this article to learn the compound ratio formula in math, how to solve ratio sums, and more.

Step-by-step explanation:

A compound or mixed ratio is defined as the ratio whose antecedent is the product of the antecedents of two or more simple ratios and its consequent is the product of the consequents of those ratios.

The required compound ratio is

$= \frac{4}{5} \times \frac{8}{9} \times \frac{12}{13}$

$= \frac{128}{195}$
