Example 1:

Given that y varies proportionally with x , with a constant of proportionality k=1/3 , find y when x=12 .

Write the equation of the proportional relationship.

The variable x varies proportionally with y with a constant of proportionality equal to 1/3

So, y=1/3x

Substitute the given x value.

y=1/3×12

y=4
