2 Ratios and Proportional Relationships
Using fractions, decimals, and percent to represent equal numeric relationships.

3 Essential Question What is the difference between ratios, rates, unit rates, and proportions?

4 Ratio and Rates Pat’s Flower Shop specializes in growing and selling large daisies. On a typical summer day, you may hear a florist say one of these statements: In the Daisy Smile Bouquet, there are 2 white daisies for every 3 orange daisies. In the Daisy Smile Bouquet, 2 out of every 5 daises are white. Five daisies cost $7.50. There are 10 daisies in a small vase.

5 Vocabulary Ratio: A comparison of two quantities using the same unit of measure. Relación: Una comparación de dos cantidades usando la misma unidad de medida. Part to Part Ratio: In the Daisy Smile Bouquet, there are 2 white daises for every 3 orange daisies. Relación de parte a parte: en el ramo de la sonrisa de Margarita, hay 2 margaritas blancas para cada 3 margaritas naranja. Part to Whole Ratio: In the Daisy Smile Bouquet, 2 out of every 5 daisies are white. Parte entera de la relación: en el ramo de la sonrisa de Margarita, 2 de cada 5 margaritas son de color blanco.
