Alguien me ayuda

Answer 1

Respuesta:

a) 9.2

b) 0.6190476190476191

Explicación paso a paso:

$5 \frac{ 1 }{5} + 2 \frac {8 }{4} = 5 \frac{1 }{5} + 4 = 5 + \frac{ 1 }{5} + 4 = 9 +\frac{ 1 }{5} = 9 \frac{1 }{5} = 9.2$

$2\frac{ 2} {7} - 1 \frac {4 }{6} = \frac { 2 + 2\cdot7} {7} - \frac { 4 + 1\cdot6} {6} = \frac{16} {7} - \frac {10} {6} = \frac{ 16\cdot6} {7\cdot6} - \frac {10\cdot7} {6\cdot7} =\frac { 96} {42} - \frac {70 }{42} = \frac{ 96 - 70} {42} = \frac {26 }{42}$
