Which expression is equivalent to the following complex fraction? 1+1/y /1-1/y

Step-by-step explanation:

To solve a complex fraction like , take LCM of both the terms separately first to get:

 =

and

Now combine and divide these terms to get:

The term in both the denominators will be cancelled out by each other and you will be left with:

Therefore, the expression is equivalent to the given complex fraction.

Answer

(y + 1) / (y - 1)

Explanation

(1 + 1/y) / (1 - 1/y)

1+1/y = 1/y(y + 1)

          =  (1/y)(y + 1)

1 - 1/y = (1/y)(y - 1)

         = (1/y)(y - 1)

∴ (1/y)(y + 1) / (1/y)(y - 1)  = (y + 1) / (y - 1)
