Question

Multiplicative inverse of \(- 1\frac{1}{5}\) is
1. 5/6
2. \(1\frac{1}{5}\)
3. -5/6
4. -6/5

Answer 1

Correct Answer - Option 3 : -5/6

Given:

Number = \(- 1\frac{1}{5}\) = - 6/5

Concept:

Multiplicative inverse = It is defined as a number which when multiplied by the original number, will give the result as 1.

Calculation:

Let the multiplicative inverse of - 6/5 is b. 

So, - 6/5 × b = 1 

⇒ - b = 5/6

⇒ b = - 5/6 

∴ The required result is - 5/6.
