[tex]-\frac{4}{6} + -\frac{7}{9}[/tex] = [tex]-\frac{13}{9}[/tex]
Step 1: Cancel 4/6 and change to 2/3.
[tex]= -\frac{2}{3} - \frac{7}{9}[/tex]
Step 2: Adjust Fractions based on the LCM.
The LCM of 3 , 9 : 9
[tex]= -\frac{6}{9} - \frac{7}{9}[/tex]
[tex]= \frac{-6 - 7}{9}[/tex]
Step 3: Subtract the numbers : - 6 -7 = -13
[tex]= -\frac{13}{9}[/tex]
