In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

• A.

English

• B.

Greek

• C.

Latin

• D.

French

B. Greek
Explanation
The word "ratio" originated from the Greek language. The term "ratio" in Greek means "reason" or "proportion." The Greeks were known for their mathematical and philosophical contributions, and they developed the concept of ratio as a way to express the relationship between two quantities. This term has been adopted and used in various fields, including mathematics, economics, and science, to describe the comparison or proportion between different values.

### ..... developed a theory of ratio and proportion as applied to numbers.

• A.

The Pythagoreans

• B.

Euclid

• C.

Bertolt Bretch

• D.

Newton

A. The Pythagoreans
Explanation
The Pythagoreans developed a theory of ratio and proportion as applied to numbers. This ancient Greek philosophical and mathematical school, founded by Pythagoras, believed that numbers were the foundation of everything in the universe. They studied the relationships between numbers and discovered the principles of ratios and proportions. Their work laid the foundation for modern mathematics and influenced the development of Euclidean geometry. Euclid, although a renowned mathematician, did not specifically develop a theory of ratio and proportion as applied to numbers. Bertolt Brecht and Newton were not known for their contributions to this field.

### The discovery of a theory of ratios that does not assume commensurability is probably due to .....?

• A.

The Pythagoreans

• B.

Eudoxus of Cnidus

• C.

Euclid

• D.

Aristotle

A. The Pythagoreans
Explanation
The Pythagoreans are likely responsible for the discovery of a theory of ratios that does not assume commensurability. This is because the Pythagoreans were known for their mathematical investigations and discoveries, particularly in the field of geometry. They were interested in the relationships between numbers and ratios, and their work laid the foundation for many mathematical concepts that are still used today. Therefore, it is reasonable to attribute the discovery of a theory of ratios without assuming commensurability to the Pythagoreans.
