Question

A ratio expressed in lowest form has no common factor other than ______ in its terms.

Answer 1

A ratio expressed in lowest form has no common factor other than one in its terms.

Explanation:

When a ratio is in its lowest form, the greatest common divisor (GCD) of the two numbers is 1, meaning they are coprime. In other words, there is no common factor between the two terms except for 1. For example, the ratio 6 : 8 can be simplified to 3 : 4 because 3 and 4 have no common factors other than 1.
