Question

Giúp mình với 

3/5 : x = 3 x 1/2

Answer 1

`3/5 : x=3 xx 1/2`

`=> 3/5 :x=3/2`

`=> x= 3/5 : 3/2`

`=> x= 3/5 xx 2/3`

`=> x= 6/15`

`=> x= 2/5`

Vậy `x=2/5`

Answer 2

\(\dfrac{3}{5}:x=3\times\dfrac{1}{2}\)
\(\dfrac{3}{5}:x=\dfrac{3}{2}\)
\(x=\dfrac{3}{5}:\dfrac{3}{2}\)
\(x=\dfrac{2}{5}\)
#die

Answer 3

\(\dfrac{3}{5}\div x=3\times\dfrac{1}{2}\)

\(\dfrac{3}{5}\div x=\dfrac{3\times1}{1\times2}\)

\(\dfrac{3}{5}\div x=\dfrac{3}{2}\)

\(x=\dfrac{3}{5}\div\dfrac{3}{2}\)

\(x=\dfrac{3}{5}\times\dfrac{3}{2}\)

\(x=\dfrac{3\times3}{5\times2}\)

\(x=\dfrac{9}{10}\)
