When evaluating negative numbers the farther they are from zero the lesser they are. In this case we have -26/9 and -2.75 we need to first convert the fraction to a decimal in order to compare them
[tex]\frac{-26}{9}=-2.888\ldots[/tex]The value of -28/9 is equal to -2.888... This is farther from zero than -2.75, therefore:
[tex]-\frac{26}{9}<-2.75[/tex]The signal that belongs to the blank is "<".
