Rates and Ratios in Real Life

Mrs. Lehmann reviews homework on ratios to rates and explains how to calculate unit rates using examples like Angela's swimming. The lesson then covers converting rates back into ratios, with practical examples such as Dave's pool cleaning and Emmaline's typing. The video concludes with guidance on setting up homework.
