Question

second and third terms of a proportion are called the dess term
​

Answer 1

Answer:

We will learn how to solve proportion problems. We know, the first term (1st) and the fourth term (4th) of a proportion are called extreme terms or extremes, and the second term (2nd) and the third term (3rd) are called middle terms or means. Therefore, in a proportion, product of extremes = product of middle terms.
