Question

1) Efetue as divisões:
a) (+173): (+2/3) =
b) (+4/7):(-2/5) =
c) (-3/5) : (-3/7) =​

Answer 1

Resposta:

a) $=\frac{519}{2} = 259,5$

b) $=-\frac{10}{7} = -1,43$

c) $=\frac{7}{5} = 1,4$

Explicação passo-a-passo:

$a) \frac{173}{\frac{2}{3} } = \frac{173*3}{2} = \frac{519}{2} = 259,5$

$b) \frac{\frac{4}{7} }{\frac{-2}{5} } = \frac{4}{7} * \frac{5}{-2} = - \frac{20}{14} = - \frac{10}{7} = - 1,43$

$c) \frac{\frac{-3}{5} }{\frac{-3}{7} } = \frac{-3}{5} * \frac{7}{-3} = \frac{7}{5}$
