Answer:
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
