Using cross product to verify a proportion

The video tutorial explains how to determine if two fractions form a proportion. It begins by defining a proportion as two equivalent fractions. The instructor demonstrates checking equivalence by comparing division results and using cross multiplication. The tutorial concludes that the given fractions do not form a proportion as they fail both equivalence checks.

What conclusion can be drawn from the cross multiplication of 60 and 48?

Based on the analysis of the fractions, do 16/15 and 4/3 form a proportion? Explain your reasoning.
