GCSE Secondary Maths Age 13-17 - Ratio, Proportion & Rates of Change: Density, Mass, Volume - Explained

The video tutorial explains how to calculate the density of a new liquid, C, formed by mixing two liquids, A and B, with known masses and densities. The instructor uses the mass-density-volume triangle to solve the problem, calculating the volumes of liquids A and B first, then finding the total volume and density of liquid C. The tutorial emphasizes the importance of understanding the relationship between mass, density, and volume, and how remembering these triangles can simplify problem-solving.
