What's the numerator for the following rational expression? 6/t+7/t=?/t
Svetlanka [38]

The numerator for the following rational expression is 13

<h3>How to determine the numeration?</h3>

The rational expression is given as:

6/t + 7/t

Take the LCM of the denominator;

The LCM of t and t is t

So, we have:

6/t + 7/t = (6 + 7)/t

Evaluate the sum

6/t + 7/t = 13/t

13 is the numerator, while t is the denominator

Hence, the numerator for the following rational expression is 13
