Answer 1

Explicación paso a paso:

$1) \\ \frac{3}{8} - \frac{2}{16} = \frac{6 - 2}{16} = \frac{4}{16} = \frac{1}{4} \\ \\ 2) \\ \frac{4}{25} - \frac{1}{195} = \frac{156 - 1}{975} = \frac{155}{975} = \frac{31}{195} \\ \\ 3) \\ \frac{8}{15} + \frac{3}{6} = \\ \\ \frac{8}{15} + \frac{1}{2} = \frac{16 + 15}{30} = \frac{31}{30} \\ \\ 4) \\ \frac{4}{11} + \frac{2}{200} = \\ \\ \frac{4}{11} + \frac{1}{100} = \frac{400 + + 11}{1.100} = \frac{411}{1.100}$
