英文词源

ratio (n.): 1630s, "reason, rationale," from Latin ratio "reckoning, numbering, calculation; business affair, procedure," also "reason, reasoning, judgment, understanding," from rat-, past participle stem of reri "to reckon, calculate," also "think" (see reason (n.)). Mathematical sense "relationship between two numbers" is attested from 1650s.

中文解释

分析：ra——“热爱”的拼音首字母；ti——“踢”的拼音；o——外形像球。记忆：热爱踢球的人在人群中的比率还是很高的。
