Answer 2

Respuesta:

$\frac{9 }{12} \div(\frac{- 1} {5}) = - \frac{9 }{12} \div \frac { 1} {5} = - \frac {3\cdot3 }{4\cdot3} \div \frac {1 }{5} = -\frac { 3 }{4} \div \frac{ 1 }{5} = - \frac{3 }{4} \cdot \frac{5 }{1} = - \frac{ 3\cdot5 }{4\cdot1} = - \frac{ 15 }{4}$

$-\frac{9 }{12} \div(\frac{- 1} {5}) = \frac{9 }{12} \div \frac { 1} {5} = \frac {3\cdot3 }{4\cdot3} \div \frac {1 }{5} = \frac { 3 }{4} \div \frac{ 1 }{5} = \frac{3 }{4} \cdot \frac{5 }{1} = \frac{ 3\cdot5 }{4\cdot1} = \frac{ 15 }{4}$

$- \frac{6 }{3} - \frac{4 }{3} = -2 - \frac{ 4 }{3} = - 2 - - \frac{4 }{3} = - 2 - \frac {4 }{3} = - 2 -\frac { 1\cdot3 + 1 }{3} = -3\frac { 1 }{3}$
