Question

a.5/8 x y =3/2

b.y:1/6=3/5

Answer 1

a) Ta có: \(\dfrac{5}{8}x=\dfrac{3}{2}\)

\(\Leftrightarrow x=\dfrac{3}{2}:\dfrac{5}{8}=\dfrac{3}{2}\cdot\dfrac{8}{5}\)

hay \(x=\dfrac{12}{5}\)

Vậy: \(x=\dfrac{12}{5}\)

Answer 2

b) Ta có: \(y:\dfrac{1}{6}=\dfrac{3}{5}\)

\(\Leftrightarrow y=\dfrac{3}{5}\cdot\dfrac{1}{6}=\dfrac{3}{30}\)

hay \(y=\dfrac{1}{10}\)

Vậy: \(y=\dfrac{1}{10}\)

Answer 3

a,\(\dfrac{5}{8}\cdot y=\dfrac{3}{2}\\ y=\dfrac{3}{2}:\dfrac{5}{8}\\ y=\dfrac{12}{5}\)

\(b,y:\dfrac{1}{6}=\dfrac{3}{5}\\ y=\dfrac{3}{5}\cdot\dfrac{1}{6}\\ y=\dfrac{1}{10}\)

Answer 4

a) 5/8 x y =3/2

          y=3/2:5/8

           y=12/5

b) y:1/6=3/5

     y      =3/5x1/6

     y       =1/10
