4. The multiplicative inverse of -100 is --​

Answer 1

Answer:

Firstly you always remember that reciprocal of any number is called its multiplicative inverse.

Because by multiply of both we get answer which is 1.

Multiplicative inverse of -100 is -1/100

because:-

-100×-1/100

• then we cut minus with minus
• after that we cut 100 with other 100 and the answer is 1
