Mọi người giúp mình với mình cần gấp cảm ơn mọi người 😘👉👈

Answer 1

a) \(\dfrac{5}{11}:\dfrac{5}{3}+\dfrac{7}{35}\)

= \(\dfrac{5}{11}x\dfrac{3}{5}+\dfrac{7}{35}\)

= \(\dfrac{3}{11}+\dfrac{1}{5}=\dfrac{15}{55}+\dfrac{11}{55}=\dfrac{26}{55}\)

b) \(7-\dfrac{5}{6}x5\)

= \(7-\dfrac{25}{6}\)

 

= \(\dfrac{42}{6}-\dfrac{25}{6}\)

= \(\dfrac{17}{6}\)

Answer 2

`5/11 : 5/3 + 7/35`

`=5/11 xx 3/5 + 7/35`

`=3/11 + 7/35`

`=3/11 + 1/5`

`=15/55 + 11/55`

`=26/55`

____________________________________

`7 - 5/6 xx 5`

`=7 - (5xx5)/6`

`=7 - 25/6`

`=42/6 - 25/6`

`=17/6`
