Explicación paso a paso:
La suma o resta de fracciones es una de las operaciones básicas que permite combinar dos o más fracciones
a)
[tex]\frac{4}{9} + \frac{3}{7}=\frac{(4)(7) + (3)(9) }{63} =\frac{28+27}{63} =\frac{55}{63}[/tex]
b)
[tex]\frac{8}{25} + \frac{12}{15}=\frac{(8)(3) + (12)(5) }{75} =\frac{24+60}{75} =\frac{84}{75} =\frac{28}{25}[/tex]
c)
[tex]\frac{4}{24} + \frac{6}{32}=\frac{(4)(4) + (6)(3) }{96} =\frac{16+18}{96} =\frac{34}{96} =\frac{17}{48}[/tex]
d)
[tex]\frac{4}{9} + \frac{11}{7}=\frac{(4)(7) + (11)(9) }{63} =\frac{28+99}{63} =\frac{127}{63}[/tex]
e)
[tex]\frac{5}{12} + \frac{2}{12}=\frac{(5)+(2)}{12} =\frac{7}{12}[/tex]
f)
[tex]\frac{4}{3} + \frac{7}{5}=\frac{(4)(5) + (7)(3) }{15} =\frac{20+21}{15} =\frac{41}{15}[/tex]
