1 Proportions and Problem Solving Section 6.3

2 A 16-oz Cinnamon Mocha Iced Tea at a local coffee shop has 80 calories. How many calories are there in a 28-oz Cinnamon Mocha Iced Tea? 2 Solving Problems by Writing Proportions Solve the proportion. Cross multiply. Simplify the right side. Divide both side by 140. A 28-oz Cinnamon Mocha Iced Tea has 140 calories. Martin-Gay, Prealgebra, 5ed

3 Helpful Hint When writing proportions to solve problems, write the proportions so that the numerators have the same unit measures and the denominators have the same unit measures. For example, 3 Martin-Gay, Prealgebra, 5ed
