Answer 1

To determine which set of ratios forms a proportion, we need to compare the ratios to see if they are equivalent.

For the first set:
5:10 is equivalent to 1:2
20:40 is equivalent to 1:2

So, the first set of ratios, 5:10 and 20:40, forms a proportion because they reduce to the same equivalent ratio of 1:2.
