Ratio and Proportion

This CTET Paper 2 Mathematics chapter builds a bilingual, publish-ready view of Ratio and Proportion for Classes VI–VII: ratio as comparison, simplest form, equivalent ratios, proportion a:b = c:d, unitary method, light continued proportion, map-scale and recipe contexts, part-to-part versus part-to-whole pedagogy, TLM, misconceptions, worked caselets, exam application, common errors and revision — with standalone Ratio (c1-1-03) as one-line sibling only.
