A recipe book shows measurement conversions for cups to pints. It shows that 3 cups converts to 1.5 pints and 5 cups converts to 2.5 pints. Write an equation that shows the proportional relationship between pints and cups where p represents pints and n represents cups. p equals 3 over 1.5 times n n equals 1.5 over 3 times p p = 0.5n n = 0.5p
