Question

what is the multiplicative inverse of -1/9

Answer 1

Let b be the multiplicative inverse of a such ab=1

Answer 2

S the multiplicative inverse of -1/9 is b and a is -1/9
Solve for the multiplicative inverse of -1/9

Answer 3

In other words, solve for b

Answer 4

ab=1
a*b=1
-1/9 * b=1 <---solve for b
Can you do this?

Answer 5

you lost me big time e.0???

Answer 6

Your question ask us to find the multiplicative inverse of a
I'm calling that multiplicative inverse b.
The multiplicative identity is 1.
If a and b are multiplicative inverses of each other, then the product of a and b is 1.

Answer 7

ab=1
-1/9 * b=1
You need to solve this for b in other words.

Answer 8

If you don't know how to solve equations, then you can always remember to take the opposite of the reciprocal.
Just so you know 0 doesn't have a multiplicative inverse.

Answer 9

What is the reciprocal of -1/9?

Answer 10

To find the reciprocal just switch the numerator and denominator for each other.

Answer 11

Do you know what I mean?

Answer 12

Opposite of the reciprocal? Multiplicative inverse IS reciprocal.

Answer 13

Oops. I'm thinking of lines that are perpendicular. I'm sorry.

Answer 14

Just flip it. lol.

Answer 15

:)

Answer 16

But still ab=1
then a and b are multiplicative inverses of each other
