Question

Giải chi tiết giúp mik nha!!

Answer 1

\(y:\dfrac{3}{11}=\dfrac{7}{6}+\dfrac{2}{3}\)

\(y:\dfrac{3}{11}=\dfrac{11}{6}\)

\(y=\dfrac{11}{6}\times\dfrac{3}{11}\)

\(y=\dfrac{1}{2}\)

Bài 3

\(\dfrac{3}{7}:\dfrac{1}{4}-\dfrac{1}{2}=\dfrac{3}{7}\times\dfrac{4}{1}-\dfrac{1}{2}=\dfrac{12}{7}-\dfrac{1}{2}=\dfrac{24}{14}-\dfrac{7}{14}=\dfrac{17}{14}\)

Answer 2

`2)`

`y:3/11=7/6+2/3`

`y:3/11=11/6`

`y=11/6xx3/11`

`y=1/2`

`3)`

`=12/7-1/2=24/14-7/14=17/14`
