# Unit 5

# Ratios, Rates & Proportions

#### Unit 5 focuses on comparing values of the same units as well as different units using Ratios & Rates, while also Solving Proportions using Equivalent Rates & Ratios. Ratios are expressed using a Fraction Bar, Colon, and Words, and Rates are Rewritten as Unit Rates to compare Price Rates to determine better value. Equivlanent Ratios & Rates are demonstrated through Ratio Tables as well as Linear Graphs depicting their relationship on a Coordinate Plane. Finally, Rates & Ratios are utilized to Convert between different Units and Rates using Dimensional Analysis.
