Question

\(\dfrac{5}{9}:\left(\dfrac{1}{11}-\dfrac{5}{22}\right)+\dfrac{5}{9}:\left(\dfrac{1}{15}-\dfrac{2}{3}\right)\)

Answer 1

`5/9 : (1/11 - 5/22) + 5/9 : (1/15 -2/3)`

` = 5/9 : ( -3/22) + 5/9 : (-3/5)`

` = 5/9 xx (22/(-3)) + 5/9 xx (5/-3)`

` = 5/9 xx ( 22/(-3) + 5/(-3))`

` = 5/9 xx (-9)`

` = (-45)/9`

`= -5`

Answer 2

kết quả là        -5 nha bn 

Answer 3

5/9 : [(1/11 - 5/22) + (1/15 - 2/3)]

= 5/9 : [-3/22 + -3/5]

= 5/9 : -81/110

= -550/729

Answer 4

Answer 5

\(=\dfrac{5}{9}:\left(-\dfrac{3}{22}\right)+\dfrac{5}{9}:\left(-\dfrac{3}{5}\right)\)

\(=-\dfrac{5}{9}.\dfrac{22}{3}-\dfrac{5}{9}.\dfrac{5}{3}\)

\(=-\dfrac{110}{27}-\dfrac{25}{27}=-5\)

Answer 6

`5/9 : (1/11 - 5/22) + 5/9 : ( 1/15 - 2/3)`

`= 5/9 : -3/22 + 5/9 : -3/5`

`= 5/9 xx -22/3 + 5/9 xx -5/3`

`= 5/9 xx (-22/3 + -5/3)`

`=5/9 xx -9`

`=-5`
