Answer 2

Step-by-step explanation:

Let x kg of food will be required by 12 cows.

$\therefore \: \frac{13.5}{9} = \frac{x}{12} \\ \implies \: x = \frac{13.5 \times 12}{9} \\ \implies \: x = \frac{13.5 \times 4}{3} \\ \implies \: x = 4.5 \times 4 \\ \implies \: x = 18$

Thus 12 cows would require 18 kg of food supplement.
