Topic 2: Fractional Rates
Topic Overview:
In this topic, students extend their work with rates to include rates with fractional values.
Standards:
MGSE7.RP.1 Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction (1/2)/(1/4) miles per hour, equivalently 2 miles per hour .
MGSE7.RP.2c Represent proportional relationships by equations. For example, if total cost π‘ is proportional to the number π of items purchased at a constant price π, the relationship between the total cost and the number of items can be expressed as π‘ = ππ.
MGSE7.RP.3 Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, and fees.
