4/5+1/7=
2/3+1/9=
1/5+4/3=
PORFAAAS AYUDAMEEEE

Answer 1

Explicación paso a paso:

$\frac{5}{6} + \frac{1}{12} = \frac{1 0 + 1}{12} = \frac{11}{12} \\ \\ \frac{1}{7} + \frac{8}{21} = \frac{3 + 8}{21} = \frac{11}{21} \\ \\ \frac{4}{5} + \frac{1}{7} = \frac{28 + 5}{35} = \frac{33}{35} \\ \ \\ \frac{2}{3} + \frac{1}{9} = \frac{6 + 1}{9} = \frac{7}{9} \\ \\ \frac{1}{5} + \frac{4}{3} = \frac{3 + 20 }{15} = \frac{23}{15}$
