This math topic focuses on practicing the calculation of unknown lengths using ratios, demonstrated within various geometrical contexts. Students are required to solve for unknown line lengths given certain dimensions and relative ratios. The problems are complemented by visual aids (SVG images) that likely display lines and angles to contextualize the questions. Each problem is detailed with a specific line to solve for, and potential answers are presented as decimal numbers, indicating a need for precise calculation and understanding of decimal and ratio applications in geometry.
