Answer 2

To Find :- Multiplication inverse of (-2021) ?

Concept used :-

• The multiplicative inverse of a number is the number which when multiplied by the original number gives the result as 1 .
• The multiplicative inverse of a = 1/a .
• The multiplicative inverse of a/b = b/a .

Solution :-

Let us assume that, the multiplicative inverse of (-2021) is x .

So,

→ Original number × multiplicative inverse = 1

→ (-2021) × x = 1

→ x = 1/(-2021)

→ x = (-1/2021)

Verification :-

→ (-2021) × (-1/2021) = 1

→ (-1)(2021) × {(-1)/(2021)} = 1

→ (-1) × (-1) = 1

→ 1 = 1

→ LHS = RHS

therefore, the multiplicative inverse of (-2021) is equal to (-1/2021) .
