Question

\(\dfrac{2}{5}\)x  = (\(\dfrac{1}{2}\))\(^3\) : \(\dfrac{1}{2}\)
:'>?
 

Answer 1

2/5 . x = (1/2)³ : 1/2

2/5 . x = 1/8 : 1/2

2/5 . x = 1/4

x = 1/4 : 2/5

x = 5/8

Answer 2

\(\Leftrightarrow\dfrac{2}{5}x=\left(\dfrac{1}{2}\right)^2=\dfrac{1}{4}\Leftrightarrow x=\dfrac{1}{4}\cdot\dfrac{5}{2}=\dfrac{5}{8}\)
