Question

Resolva a expressão numérica

Answer 1

Boa noite!


$[(\frac{2}{3} )^{2}* (\frac{5}{4} - \frac{1}{2} )] + \frac{2}{5} / \frac{3}{10}$

$[\frac{4}{9} * \frac{3}{4} ] + \frac{2}{5} * \frac{10}{3}$

$\frac{12}{36} + \frac{20}{15}$

$\frac{1}{3} + \frac{4}{3} = \frac{5}{3}$


Bons estudos :)
