Question

y  - 7/10 = 4/5 : 2               y x 4/9 = 3/8 x 4

Answer 1

a: =>y-7/10=4/10

=>y=11/10

b: \(\Leftrightarrow y\cdot\dfrac{4}{9}=\dfrac{3}{2}\)

hay y=27/8

Answer 2

`y-7/10=4/10`

`y=7/10+4/10`

`y=11/10`

`---------------------------------------`

`y xx4/9 =12/8=3/2`

`y=3/2:4/9`

`y=27/8`

Answer 3

y  - 7/10 = 4/5 : 2               y x 4/9 = 3/8 x 4

\(y-\dfrac{7}{10}=\dfrac{2}{5}\)                       \(y\times\dfrac{4}{9}=\dfrac{3}{2}\)

\(y=\dfrac{2}{5}+\dfrac{7}{10}\)                       \(y=\dfrac{3}{2}:\dfrac{4}{9}\)

\(y=\dfrac{11}{10}\)                               \(y=\dfrac{27}{8}\)
