This document contains notes from a math lesson on ratios of fractions and unit rates. It includes the homework assignment, which was to complete Problem Set 10, and provides the solutions. The lesson covered converting time fractions such as 10, 15, 20, 30, and 45 minutes to fractional parts of an hour. It also presented three methods - using equations, drawing a picture, and a double number line - for solving a word problem about two students running at constant rates.

Method 3 (double number line):
*How do you find the value of a 5 minute time increment? What are you
really finding?
*Why were 5 minute time increments chosen?
*What if the times had been 24 and 32, or 18 and 22?
