One way to show that two ratios are proportional is by cross multiplying.
If you have two ratios, for example, a/b and c/d, you can cross multiply by multiplying a and d, and b and c. If the two products are equal, then the ratios are proportional.
So if ad = bc, then the ratios a/b and c/d are proportional. This property can be used to prove that two ratios are proportional in various mathematical problems and calculations.
