The title of my unit is "It's Golden!". Students will interpret and use ratios in different contexts to show the relative sizes of two quantities, using appropriate notations. They will use proportions to solve problems. They will also use cross-multiplication as a method for solving proportions, understanding it as the multiplication of both sides of an equation by a multiplicative inverse
