Question

[(5sobre6-1sobre5)-1sobre3]:√9sobre4=

Por favor me ajudem

Answer 1

$[( \frac{5}{6} - \frac{1}{5})- \frac{1}{3}]: \sqrt{ \frac{9}{4} }$
$=[( \frac{5*5-1*6}{6*5} )- \frac{1}{3} ]: \frac{3}{2}$
$=[( \frac{25-6}{30} )- \frac{1}{3} ]: \frac{3}{2}$
$=( \frac{19}{30}- \frac{1}{3} ): \frac{3}{2}$
$=( \frac{19*3-1*30}{30*3} ): \frac{3}{2}$
$=( \frac{57-30}{90} ): \frac{3}{2}$
$= \frac{27}{90} : \frac{3}{2}$
$=\frac{27}{90} * \frac{2}{3}$
$= \frac{9}{45}$
$= \frac{1}{5}$

Answer 2

Oie, Td Bom?!

$= [( \frac{5}{6} - \frac{1}{5} ) - \frac{1}{3} ] \div \sqrt{ \frac{9}{4} }$

$= [( \frac{25}{30} - \frac{6}{30}) - \frac{1}{3} ] \div \sqrt{ \frac{9}{4} }$

$= [( \frac{25 - 6}{30} ) - \frac{1}{3} ] \div \sqrt{ \frac{9}{4} }$

$= [ \frac{19}{30} - \frac{1}{3} ] \div \frac{3}{2}$

$= [ \frac{19}{30} - \frac{10}{30} ] \div \frac{3}{2}$

$= [ \frac{19 - 10}{30} ] \div \frac{3}{2}$

$= \frac{9}{30} \div \frac{2}{3}$

$= \frac{9}{30} \: . \: \frac{2}{3}$

• Simplifica por 3.

$= \frac{3}{30} \: . \: 2$

• Simplifica por 2.

$= \frac{3}{15}$

$= \frac{3 \div 3}{15 \div 3}$

$= \frac{1}{5}$

$= 0,2$
