Question

Como resolvo?
[( 1 + 3 . 2 ) : 4 ] . 2
    2    4  9     5

Answer 1

$[(\frac{1}{2}+\frac{3}{4}.\frac{2}{9}):\frac{4}{5}].2=[(\frac{1}{2}+\frac{1}{6}):\frac{4}{5}].2=[(\frac{3+1}{6}):\frac{4}{5}].2=[(\frac{4}{6}):\frac{4}{5}].2$

$\frac{20}{24}.2=\frac{40}{24}=\frac{5}{3}$

Espero ter ajudado.

1+3.2=8:4=2.22495=44990
