Are 8 7–6 3 and 12–92–5252 multiplicative inverses?

To determine if two numbers are multiplicative inverses, we need to multiply them together. If the result is 1, then they are multiplicative inverses.

Let's break down the numbers:

The first number is 8/7 - 6/3 = 8/7 - 2 = 2/7.

The second number is 12/9 - 52/52 = 4/3 - 1 = 1/3.

Now, let's multiply these two numbers together:

(2/7) * (1/3) = 2/21 = 0.09523809523809523.

Since the result is not 1, the two numbers are not multiplicative inverses.
