c)1/3×(-5/4)÷(-9/11)
d)(-2/5)÷(+1/4)÷(-3/7)​

Answer 1

Resposta:

Explicação passo-a-passo:

a)

= 6÷(-1/5)

= 6 . (-5)

= - 30

b)

= 2/7÷(-3/11)

= 2/7 . (-11/3})

= -22/21

c)

= 1/3×(-5/4)÷(-9/11)

= - 5/12 . (-11/9)

= 55/108

d)

= (-2/5)÷(+1/4)÷(-3/7)​

= -2/5 . 4 : (-3/7)

= - 8/5 . (-7/3)

= 56/15
