Question

ME AJUDEM É PRA AGORA

( 10/ 3 x 1/ 2 ) - ( 12/ 7 x 8/ 5 ) : 1/ 2

Answer 1

Explicação passo-a-passo:

$( \dfrac{10}{3} \times \dfrac{1}{2}) - ( \dfrac{12}{7} \times \dfrac{8}{5} ) \div \dfrac{1}{2}$

$\dfrac{10}{6} - \dfrac{96}{35} \div \dfrac{1}{2}$

$\dfrac{10}{6} - \dfrac{96}{35} \times \dfrac{2}{1}$

$\dfrac{10}{6} - \dfrac{192}{35}$

$\dfrac{10 {}^{ \div 2} }{6 {}^{ \div 2} } - \dfrac{192}{35}$

$\dfrac{5}{3} - \dfrac{192}{35}$

$\dfrac{175 - 576}{105}$

$- \dfrac{401}{105}$
