Answer 1

Resposta:

3/2

Explicação passo a passo:

Simplifique a fracao 64/27 ÷ 128/81

= 64/27 . 81/128

= 64/128 (:64)/(:64) . 81/27

= 1/2 . 3

= 3/2

Answer 2

Resposta:

$\frac{64}{27}\div \frac{128}{81}\\\\\mathrm{Aplicar\:as\:propriedades\:das\:fracoes}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}\\\\\frac{64}{27}\times \frac{81}{128}\\\\\mathrm{Multiplicar\:fracoes}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}\\\\\frac{64\times \:81}{27\times \:128}\\\\\mathrm{Multiplicar\:os\:numeros:}\:64\times \:81=5184\\\\\frac{5184}{27\times \:128}\\\\\mathrm{Multiplicar\:os\:numeros:}\:27\times \:128=3456$

$\frac{5184}{3456}\\\\\mathrm{Eliminar\:o\:fator\:comum:}\:1728\\\\=\frac{3}{2}$
