Question

How do you do inverse operation on a fraction ( y/3 ) = -6

Answer 1

`(-1)/(18)`

Solution:

Given expression is
`(y)/(3)=-6`

To find the inverse of y.

⇒
`(y)/(3)=-6`

Do cross multiplication.

⇒ y = –6 × 3

⇒ y = –18

Inverse of y means reverse the function.

We know that inverse of y is
`(1)/(y)`.

⇒
`(1)/(y)= (-1)/(18)`

Hence, inverse of y is
`(-1)/(18).`
