ayuda wn pliiiiiis XD ​

Answer 1

Explicación paso a paso:

$\frac{1}{8} + \frac{6}{8}=\frac{(1)+(6)}{8} =\frac{7}{8} \\\\\frac{4}{3} + \frac{6}{3}=\frac{(4)+(6)}{3} =\frac{10}{3} \\\\\frac{7}{2} + \frac{9}{6}=\frac{(7)(3) +(9)(1) }{6} =\frac{21+9}{6} =\frac{30}{6} =5\\\\\frac{4}{3} + \frac{6}{4}=\frac{(4)(4) +(6)(3) }{12} =\frac{16+18}{12} =\frac{34}{12} =\frac{17}{6} \\\\\frac{10}{5} + \frac{5}{7}=\frac{(10)(7) +(5)(5) }{35} =\frac{70+25}{35} =\frac{95}{35} =\frac{19}{7}$

$\frac{10}{5} - \frac{5}{7}=\frac{(10)(7) -(5)(5) }{35} =\frac{70-25}{35} =\frac{45}{35} =\frac{9}{7} \\\\\frac{6}{4} - \frac{4}{3}=\frac{(6)(3) -(4)(4) }{12} =\frac{18-16}{12} =\frac{2}{12} =\frac{1}{6}$
