Answer 2

`=>` Gợi ý:

`9/4 - y = 1/7 : 3/6`

`9/4 - y = 2/7`

`y = 9/4 - 2/7`

`y = 55/28`

Answer 3

9/4-y=6/21

y=9/4-6/21

y=5/4

Answer 4

9/4 - y = 1/7 : 3/6

9/4 - y =  2/7

        y= 9/4- 2/7

        y=     55/28

Answer 5

\(\dfrac{9}{4}-y=\dfrac{1}{7}\div\dfrac{3}{6}\) 

\(\dfrac{9}{4}-y=\dfrac{2}{7}\) 

        \(y=\dfrac{9}{4}-\dfrac{2}{7}\) 

        \(y=\dfrac{55}{28}\)
