Answer 1

Respuesta:

$\frac{1 }{3} \cdot\frac {2 }{5} = \frac {1\cdot2 }{3\cdot5} =\frac {2 }{15}$

$\frac{3 }{2} \cdot \frac {2 }{6} = \frac { 3 }{2} \cdot \frac{ 1\cdot2 }{3\cdot2} = \frac {3 }{2} \cdot \frac{ 1 }{3} = \frac {3\cdot1 }{2\cdot3} = \frac { 3 }{6}$

$\frac{1 }{8} \div\frac {3 }{4} = \frac{1 }{8} \cdot \frac {4 }{3} = \frac {1\cdot4 }{8\cdot3} = \frac{ 4 }{24}$

$\frac{6 }{5} \div\frac {4 }{10} = \frac{ 6 }{5} \div \frac{ 2\cdot2 }{5\cdot2} \frac{6 } {5} \div\frac{ 2 }{5} = \frac {6 }{5} \cdot \frac{ 5 }2} = \frac{ 6\cdot5 }{5\cdot2} = \frac { 30 }{10}$
