Answer 1

Answer:

$\huge\red\boxed{ANSWER}$

Step-by-step explanation:

→ GIVEN :

⇒ The equality of two ratios is called proportion.

⇒  If a : b = c : d, we write a : b :: c : d and we say that a, b, c, d are in proportion.

⇒  Here a and d are called extremes, while b and c are called mean terms.

⇒  Product of means = Product of extremes.

⇒  Thus, a : b :: c : d  (b x c) = (a x d).
