Question

tìm x, 19/4 : x = 5/6 + 2/9

Answer 1

=>19/4:x=19/18

hay x=19/4:19/8=9/2

Answer 2

\(x=\dfrac{19}{4}:\left(\dfrac{5}{6}+\dfrac{2}{9}\right)=\dfrac{19}{4}:\left(\dfrac{15}{18}+\dfrac{4}{18}\right)=\dfrac{19}{4}:\dfrac{19}{18}=\dfrac{18}{4}=\dfrac{9}{2}\)

Answer 3

\(\dfrac{19}{4}:x=\dfrac{5}{6}+\dfrac{2}{9}\)

\(\dfrac{19}{4}:x=\dfrac{19}{18}\)

\(x=\dfrac{19}{4}:\dfrac{19}{18}\)

\(x=\dfrac{9}{2}\)

Answer 4

`19/4 : x = 5/6 + 2/9`

`19/4 : x = 19/18`

`x = 19/4 : 19/18`

`x = 9/2 = 4,5`

Answer 5

`19/4:x=5/6+2/9`

`19/4:x=45/54+12/54`

`19/4:x=57/54`

`x=19/4:57/54`

`x=19/4xx54/57=9/2`

Answer 6

 x = 19/4 : 19/8

 x = 9/2
