MATHS - Ratio - Inverse Proportion

This video tutorial explains inverse proportion, contrasting it with direct proportion. It uses examples like car speeds and cleaning scenarios to illustrate how inverse proportion works, where one quantity increases as the other decreases, maintaining a constant product. The video also covers mathematical representations, including equations and constants of proportionality, and explores inverse proportion involving indices. It concludes with methods to find values of variables in inverse proportion equations.
