Ik you asked for one but here's a couple: 1,2,4,8,16,32
They are proportional. If you divide 6/36 by 6 on the numerator and the denominator, you get the same fraction of 1.6.
if you make a graph and add the coordinates on the graph you can use that find out how it creates a ratio of 1:2
It would reflect over the x-axis and then reflect over the y-axis
