if they are equivalent fractions, then they are proportional.

18/72 reduces to 1/4
4/16 reduces to 1/4

so yes, these are proportional

Hello! As we can look and see, 18/72 is equivalent to 1/4 and 4/16 is equivalent to 1/4. This is because when you divide 18/72 by 18 for both top and bottom, you get 1/4. When you divide 4/16 by 4 for both top and bottom, you get 1/4. Yes. The fractions are proportional to each other.
