Question

\(\left(\dfrac{-4}{5}\right):\left(-\dfrac{5}{3}\right);\left(\dfrac{11}{4}:\dfrac{33}{16}\right)×\dfrac{-3}{5};\left(\dfrac{3}{7}+\dfrac{-2}{3}\right):\dfrac{-4}{5}\)

mn giúp em vs ạ cảm ơn mn nhìu 

mn kèm lời giải giúp em ạ

Answer 1

`(-4)/5 : (-5/3)`

`=(-4/5) xx (-3/5)`

`=(-4xx(-3))/(5xx5)`

`=12/25`

_____________________________
`(11/4 : 33/16) xx (-3)/5`

`=(11/4 xx 16/33) xx (-3)/5`

`=4/3 xx (-3)/5`

`= (4xx(-3))/(3xx5)`

`=(-12)/15`

`=(-4)/5`

__________________________________

`(3/7 + (-2)/3 ) : (-4)/5`

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

`= ( 9/21 - 14/21) : (-4)/5`

`= (-5)/21 : (-4)/5`

`= (-5)/21 xx (-5)/4`

`=` \(\dfrac{\left(-5\right).\left(-4\right)}{21.5}\)

`=25/84`
