# Q1. Observe the below table and find if x and y are directly proportional.

Calculating $\frac{x}{y}$  we get:

$\frac{5}{15}=\frac{1}{3}$            $\frac{8}{24}=\frac{1}{3}$              $\frac{12}{36}=\frac{1}{3}$

$\frac{15}{60}=\frac{1}{4}$            $\frac{18}{72}=\frac{1}{4}$

$\frac{20}{100}=\frac{1}{5}$

So, clearly $\frac{x}{y}$ equals to $\frac{1}{3},\frac{1}{4},\frac{1}{5}$  hence it is not equal to some constant value 'k'.

We can say that x and y are not directly proportional.
