THANKS FOR THE QUESTIONS

Answer 2

Step-by-step explanation:

Invertendo Property: For four numbers a, b, c, d if a : b = c : d, then b : a = d : c; that is, if two ratios are equal, then their inverse ratios are also equal.

If a : b :: c : d then b : a :: d : c.

Proof:

a : b :: c : d

⟹ \(\frac{a}{b}\) = \(\frac{c}{d}\)

⟹ \(\frac{b}{a}\) = \(\frac{d}{c}\)

⟹ b : a :: d : c
