Answer 1

Resposta:

ITEM (A)

Explicação passo-a-passo:

$0,666... = \frac{6}{9}$

$0,75 \times \frac{6}{9}$

$\frac{3}{4} \times \frac{6}{9}$

$\frac{\diagup\!\!\!\!3}{\diagup\!\!\!\!4} \times \frac{\diagup\!\!\!\!6}{\diagup\!\!\!\!9}$

$\frac{1}{2} \times \frac{3 }{3}$

$\frac{1}{2} \times \frac{\diagup\!\!\!\!3}{\diagup\!\!\!\!3}$

$\frac{1}{2}$

$\frac{1}{2} = \mathtt{0,5}$
