UNIT OVERVIEW

Students use ratios and strategies for finding equivalent fractions to solve problems and make comparisons. Students convert recipes, determine the ratio between the circumference and diameter of a circle, and use ratios to compare the density of objects. They also use ratios to describe a population using a sample of the population.
