Answer:

[tex]y = \frac{x}{2}[/tex]

Step-by-step explanation:

Given

[tex]y : x = 1 : 2[/tex]

Required

Represent as an equation

[tex]y : x = 1 : 2[/tex]

Represent as a fraction

[tex]\frac{y }{ x} = \frac{1}{ 2}[/tex]

Cross multiply

[tex]y * 2 = x*1[/tex]

Divide both sides by 2

[tex]y = \frac{x*1}{2}[/tex]

[tex]y = \frac{x}{2}[/tex]
