Question

Calcule simplifique expressao numerica [2-(3/2+1/6)]÷5/4

Answer 1

Oi :)

Segue o resultado completo: 

$[2-( \frac{3}{2} + \frac{1}{6} )]: \frac{5}{4} \\ \\ \ [2-(\frac{3*3+1*1}{6} )]: \frac{5}{4} \\ \\ \ [2-(\frac{10}{6} )]: \frac{5}{4} \\ \\ \ [ 2-\frac{5}{3}]: \frac{5}{4} \\ \\ \ [ \frac{3*2-1*5}{3}]: \frac{5}{4} \\ \\ \frac{1}{3}: \frac{5}{4} \\ \\ \frac{1}{3} . \frac{4}{5} = \boxed{\frac{4}{15} }$

Espero que goste :)
