Question

Calcule o resultado das expressões e sempre que possível simplifique-o.
a) 23: (−47)=
b) -12: (−35)=
c) 75: (−38)=
d) -35: (−13)=

Answer 1

$a) \frac{23}{-47} = -\frac{23}{47} = \frac{-23}{-47} = \frac{23}{47}$

$b) \frac{-12}{-35} = \frac{12}{35}$

$c) \frac{75}{-38} =- \frac{75}{38} = \frac{-75}{-38} = \frac{75}{38}$

$d) \frac{-35}{13} =- \frac{35}{13} = \frac{-35}{-13} = \frac{35}{13}$
