You can consider ratios as fractions exg 1; 2 is kind of like 1/2 so
40/15
we can factor out the 'ones' (exg 4/8=1/2 times 4/4 [4/4=1])
40/15
40=2*2*2*5
15=3*5
factor out the 5
2*2*2/3
8/3
to find proptional ones just multiply the top and bottom number by the same number exg
8/3 times 4/4
8/3 times 3.14/3.14
and so on
so some are
8/3
16/6
24/9
48/18
56/21
64/29

The question is a little confusing,
For something to be proportional a constant has to be involved
E. G. A is proportional to B so A = kB
Any ratio that simplifies to 8 : 3 is the same.
