Answer 1

Respuesta:

83/8

3536/693

279/20

Explicación paso a paso:

$\frac{7}{8} +\frac{19}{8} +\frac{57}{8} = \frac{7+19+57}{8} = \frac{83}{8}$

$\frac{7}{9}+\frac{15}{7} +\frac{24}{11} =\frac{7(7)(11)+15(9)(11)+24(9)(7)}{9.7.11}$ = $\frac{3536}{693}$

$\frac{7}{8} +5\frac{3}{8} +7\frac{7}{10} = \frac{7}{8} +\frac{43}{8} +\frac{77}{10} = \frac{7(10)+43(10)+77(8)}{8.10} = \frac{1116}{80} = \frac{279}{20}$
