A)-2 e 1/2
B)-1/2 e 0,2
C)12/10 e 1,2
D)2 e 1/3
Por favor a resposta completa.

Answer 1

a)
$\frac{ - 2}{ \frac{1}{2} } = - 2 \times 2 = - 4$
$b) \frac{ \frac{ - 1}{2} }{0.2} = \frac{ \frac{ - 1}{2} }{ \frac{2}{10} } = \frac{ - 1}{2} \times \frac{10}{2} = \frac{ - 10}{4} = \frac{ - 5}{2}$
c)
$\frac{ \frac{12}{10} }{1.2} = \frac{ \frac{12}{10} }{ \frac{12}{10} } = \frac{12}{10} \times \frac{10}{12} = 1$
$d) \frac{2}{ \frac{1}{3} } = 2 \times 3 = 6$
