If a line segment is divided into 4 equal parts, what is each part called?

• A. A quarter
• B. A half
• C. A third
• D. An eighth

Answer: (A)

When a line segment is divided into 4 equal parts, each part represents one-fourth of the entire segment. This fraction can also be referred to in terms of a percentage, where each of those parts constitutes 25% of the whole. The term "quarter" is specifically used to denote one part out of four equal divisions, which directly aligns with the mathematical concept of fractions.

Using the other terms: "half" refers to one part out of two equal divisions, "third" specifies one out of three equal divisions, and "eighth" indicates one out of eight equal divisions. Since none of these terms corresponds to dividing a segment into four parts, the correct term for each part in this case is indeed a quarter.
