<u>Answer:</u>
<u>
</u>
<u>Step-by-step explanation:</u>
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.
