C) (-3/5):(+3/7)
D) (+3/7):(-2/3)​

Answer 1

Resposta:

a) (1/3) / (2/5) = (5/6) = 0,833.......

b) (-4/7) / (-2/5)=  (-20/-14) = 1.428

c) (-3/5) / (3/7) = (-21/15) = -1,4

d) (3/7) / (-2/3) = (9/-14) = -0.642

Explicação passo-a-passo:

Answer 2

Resposta:

$a) \frac{ + 1}{ 3} \times \frac{ + 5}{2} = \frac{ + 5}{6} \\ b) \frac{ - 4}{7} \times \frac{ 5}{ - 2} = \frac{ - 20}{ - 14} \\ c) \frac{ - 3}{5 } \times \frac{7}{3} = \frac{ - 21}{15} \\ d) \frac{3}{7} \times \frac{3}{ - 2} = \frac{9}{ - 14}$
