Question

8/6+3/11=...
21/15+8/3=
8/7-3/8=
9/3-8/7=
10/6-4/8=
5/6+1/21=

Answer 1

$\frac{8}{6} + \frac{3}{11} = \frac{53}{33 } \\ \frac{21}{15} + \frac{8}{3} = \frac{61}{15} \\ \frac{8}{7} - \frac{3}{8} = \frac{43}{56}$
$\frac{9}{3 } - \frac{8}{7} = \frac{13}{7} \\ \frac{10}{6} - \frac{4}{8} = \frac{7}{6} \\ \frac{5}{6} + \frac{1}{21} = \frac{37}{42}$
¡Espero te sirva!
