NY-7.RP.1Compute unit rates associated with ratios of fractions including ratios of lengths areas and other quantities measured in like or different units.→NY-7.RP.2Recognize and represent proportional relationships between quantities. Decide whether two quantities are in a proportional relationship. Identify the constant of proportionality (unit rate) in tables graphs equations diagrams and verbal descriptions.→NY-7.RP.3Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest tax markups and markdowns gratuities and commissions fees percent increase and decrease percent error.→NY-7.NS.1Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.→
