Question

calcule o resultado de cada expressão
[3/4-(5/3-3/2)]+(6/5-1)*8

Answer 1

Olá!

$\left[\dfrac{3}{4} -\left(\dfrac{5}{3}-\dfrac{3}{2} \right)\right]+\left(\dfrac{6}{5}-\dfrac{1}{1} \right)\cdot 8\\ \\ \\ \left[\dfrac{3}{4} -\left(\dfrac{10-9}{6} \right)\right]+\left(\dfrac{6}{5}-\dfrac{1}{1} \right)\cdot 8\\ \\ \\ \left[\dfrac{3}{4} -\dfrac{1}{6} \right]+\left(\dfrac{6}{5}-\dfrac{1}{1} \right)\cdot 8\\ \\ \\\left[\dfrac{18-4}{24} \right]+\left(\dfrac{6}{5}-\dfrac{1}{1} \right)\cdot 8\\ \\ \\ \dfrac{14}{24} +\left(\dfrac{6}{5}-\dfrac{1}{1} \right)\cdot 8$

$\dfrac{14}{24} +\left(\dfrac{6-5}{5}\right)\cdot 8\\ \\ \\ \dfrac{14}{24} +\left(\dfrac{1}{5}\right)\cdot 8\\ \\ \\ \dfrac{14}{24} +\dfrac{8}{5}\\ \\ \\ \dfrac{7}{12} +\dfrac{8}{5}\\ \\ \\ \dfrac{35+96}{60} \\ \\ \\ \boxed{\dfrac{131}{60}}$

Oie, Td Bom?!

$= [\frac{3}{4} - ( \frac{5}{3} - \frac{3}{2} )] + ( \frac{6}{5} - 1) \: . \: 8$

$= [ \frac{3}{4} - ( \frac{10 - 9}{6} ) ] + ( \frac{6 - 5}{5}) \: . \: 8$

$= [ \frac{3}{4} - \frac{1}{6} ] + \frac{1}{5} \: . \: 8$

$= [ \frac{9 - 2}{12} ] + \frac{1}{5} \: . \: 8$

$= \frac{7}{12} + \frac{1}{5} \: . \: 8$

$= \frac{7}{12} + \frac{8}{5}$

$= \frac{35 + 96}{60}$

$= \frac{131}{60}$
