Question

In a : b = c : d, b and c are called

Answer 1

Step-by-step explanation:

b and c are called ratio brand

Answer 2

In a:b = c:d b and c are called the mean terms.

• When two ratios are given in such a way that both are equivalent, the two are said to be in proportion.
• Such a relation, called proportion, is represented by the "::", or "=" sign.
• For example, as in the problem itself, it is given that a:b = c:d. It shows that the ratio a:b is equivalent to the ratio c:d. It means that the fraction a/b is in proportion with c/d.
• In a proportion a:b::c:d or a:b = c:d, the terms a, d are called extremes, and, b, c are called the mean terms.
