Two numbers or variables are directly proportional if their ratio is constant.
Put another way, two numbers or variables are directly proportional if one of them is a constant multiple of the other.
a is proportional to b ( a ∝ b ) if
a/b= constant or equivalently a=b x (constant)
When to numbers or variables are directly proportional, if one doubles the other doubles,
if one is halved the other is halved, etc.
