Proportions

How do we solve proportions by using cross product?

If you want to find a proportion you have to cross product or cross multiply. 8 4 that will be proportional. - * -
5 3


The thing that you cannot find a proportion without two fraction because it will not make any type sense. The reason why you need to have two fractions because you need to cross multiply.
