Answer 2

Answer:

Option 2) 0.4 is the correct answer.

Step-by-step explanation:

Multiplicative inverse of any number, when is multiplied with the original number, produces 1.

Let's assume that, the multiplicative inverse is x.

Therefore, $2\frac{1}{2} . x = 1$

$=> 5x = 2$

∴ $x = \frac{2}{5} = \frac{4}{10} = 0.4$

Option 2) 0.4 is the correct answer.
