Explicación paso a paso:
La suma o resta de fracciones es una de las operaciones básicas que permite combinar dos o más fracciones:
[tex]\frac{11}{3} + \frac{2}{9}- \frac{5}{12}=\frac{(11)(12) +(2)(4) -(5)(3) }{36} =\frac{132+8-15}{36} =\frac{125}{36}[/tex]
[tex]\frac{4}{5} - \frac{2}{3}- \frac{7}{6}=\frac{(4)(6) -(2)(10) -(7)(5) }{30} =\frac{24-20-35}{30} =\frac{-31}{30}[/tex]
[tex]\frac{1}{9} - \frac{4}{9}=\frac{(1)-(4)}{9} =\frac{-3}{9} =\frac{-1}{3}[/tex]
[tex]\frac{5}{7} + \frac{1}{7}=\frac{(5)+(1)}{7} =\frac{6}{7}[/tex]
\frac{11}{3} + \frac{2}{9}- \frac{5}{12}=\frac{(11)(12) +(2)(4) -(5)(3) }{36} =\frac{132+8-15}{36} =\frac{125}{36}
