Answer 1

¡¡¡Holaaaaa!!!

2/5-2/6=

$\frac{2}{5} - \frac{2}{6} = \frac{2}{5} + \frac{ - 2}{6} = \frac{ 2}{5} + \frac{ - 1}{3} = \frac{6}{15} + \frac{ - 5}{15} = \frac{6 + - 5}{15} = \frac{1}{15}$

1/2-1/4+3/8=

$\frac{1}{2} - \frac{1}{4} + \frac{3}{8} = \frac{1}{4} + \frac{3}{8} = \frac{5}{8}$

1/3+8/9-25/27=

$\frac{1}{3} + \frac{8}{9} - \frac{25}{27} = \frac{11}{9} - \frac{25}{27} = \frac{8}{27}$

3/4-7/5+3/10=

$\frac{3}{4} - \frac{7}{5} + \frac{3}{10} = \frac{ - 13}{20} + \frac{3}{10} = \frac{ - 7}{20}$

saludosxd!

y por cierto la ecuador número 2 no la e entendido lo siento.
