x=0.2

Step-by-step explanation:

We have been given that variables y and x have a proportional relationship, therefore, we can represent this information as:

y=kx , where k is proportionality constant.

Let us find our proportionality constant by substituting x=3 and y=15 in our above equation.

$15=k\cdot 3$

$k=\frac{15}{3}$

k=5

Now we will substitute k=5 and y=4 in our equation to find the value of x.

$4=5\cdot x$

$x=\frac{4}{5}$

x=0.2

Therefore, the value of x will be 0.2.
