Given:
Equations using properties.
To find:
The equation which use the inverse property of multiplication.
Solution:
Inverse property of multiplication:
The product of any number and its reciprocal is always 1.
Let us select the option which uses inverse property of multiplication.
Option A:

Inverse of
is
. Their product is 1.

This equation uses the inverse property of multiplication.
Option B:

Inverse of
is

So, it is not true equation.
Option C:

Inverse of
is
.
So, it is not true equation.
Option D:
![\left[7 \cdot\left((5)/(7)-(4)/(7)\right)\right]+8=9](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ozhev45va3bd34g8w1u06yedczry6qz7wm.png)
Here also inverse property is not used.
So, it is not true equation.
Hence the equation use the inverse property of multiplication is
.
