Answer 2

Answer:

here it is,

Step-by-step explanation:

Firstly take the L.C.M of the given denominators i.e 8, 16 and 12.

So, the L.C.M is 48.

Then, just solve the equation as:

138/48 + 39/48 - 28/48 = 149/48

The multiplicative inverse = 48/149.

For your understanding, you can also check it as:

Number × Multiplicative inverse = 1

So,

149/48 × 48/149 = 1

Therefore, 48/149 is the multiplicative inverse of 149/48.
