# Q1. Observe the following tables and find if x and y are directly proportional.

If we want to know that they are directly proportional, then we calculate   $\small \frac{x}{y}$  :
$\small \frac{x}{y}=\frac{20}{40} = \frac{17}{34}=\frac{14}{28}=\frac{11}{22}=\frac{8}{16}=\frac{5}{10}=\frac{2}{4}=\frac{1}{2}$ .
Hence we can say that x and y are directly proportional as $\small \frac{x}{y}$ cames out to be a constant equals $\small \frac{1}{2}$.
