1,5 × 0,555

3/2 × 5/9

15/18 ===> : (3/3)

5/6 ✓

Answer 2

Explicação passo-a-passo:

Tranformar 1,5 em fração

$1,5={15\over10}~~~simplificando~~{15:5\over10:5}={3\over2}$

Calcular a dízima

$x=0,555..\\ 10x=5,555\\ \\ 10x-x=5,55-0,555\\ 9x=5\\ x={5\over9}\\ \\ Multiplicando\\ \\ {3\over2}\times{5\over9}={3\times5\over2\times9}={15\over18}~~simplificando~~{15:3\over18:3}=\fbox{ {5\over6} }$
