Question

Multiplicative inverse of 1 upon -7

Answer 1

Given :- Multiplicative inverse of 1 upon -7 ?

Solution :-

we know that,

• Multiplicative inverse of a number * original number = 1 .

so, Let Multiplicative inverse of (1/-7) is x .

then,

→ (1/-7) * x = 1

→ x = (-7/1)

→ x = (-7)

hence, Multiplicative inverse of (1/-7) is = (-7) .

Answer 2

Given:

$\dfrac{1}{-7}$

To find:

Multiplicative inverse

Solution:

• The word 'inverse' is also known as 'reciprocal'.
• It refers to something opposite in position.
• The multiplicative inverse of a fraction a/b is b/a.
• In multiplicative inverse property, the product of a number and its multiplicative inverse is 1.

The Multiplicative inverse of:

$=> \dfrac{1}{-7}$

$=> \dfrac{-7}{1} = -7$

Hence, the Multiplicative inverse of 1/-7 is -7.
