Question

Find the multiplicative inverse of -1.1.

Answer 1

Consider the number a. The multiplicative inverse of a is 1/a. Then, if a=-1.1, its multiplicative inverse would be:

`a^(-1)=(1)/(-1.1)=\text{ -}(1)/(1.1)=\text{ -}(10)/(11)=\text{ -0.9}`

so that, we can conclude that the correct answer is:

`\text{-}(1)/(1.1)`
