Question

1 ) 7/3+8/4+7/2
2)6/8+8/2+5/16
3)10/20+8/2+11/2
4)6/5+9/10+7/2

Answer 1

Respuesta:

$\frac{7}{3} + \frac{8}{4} + \frac{7}{2} \\ = \frac{7 }{3} + \frac{8}{4} = \frac{28 + 24}{12} = \frac{52}{12} = \frac{26}{6} = \frac{13}{3} \\ \frac{13}{3} + \frac{7}{2} = \frac{26 + 21}{6} = \frac{47}{6}$

$\frac{6}{8} + \frac{8}{2} + \frac{5}{16} \\ \frac{6}{8} + \frac{8}{2} = \frac{12 + 64}{16} = \frac{76}{16} = \frac{38}{8} = \frac{19}{4} \\ \frac{19}{4} + \frac{5}{16} = \frac{304 + 20}{64} = \frac{324}{64} = \frac{162}{32} = \frac{81}{16}$

Se realizan asi no tengo mas tiempo sino t las resolveria completas, espero ayudarte
