### PRODUCT DESCRIPTION

I've created this assessment to test my students' understanding of Ratios of Fractions and Their Unit Rates. This test is composed of 3 word problems (the first has 2 parts, the second has 3, and the third has 5) and 3 spiral review problems. The Common Core State Standards ( 7.RP.A.2 Recognize and represent proportional relationships between quantities. 1. Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin. 2. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. 3.Represent proportional relationships by equations. For example, if total cost, t, is proportional to the number, n, of items purchased at a constant price, p, the relationship between the total cost and the number of items can be expressed as t = pn. 4.Explain what a point (x,y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0,0) and (1,r), where r is the unit rate.
7.RP.A.3 Use 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. ) are on the test. This is editable. At the point values I have selected, the test is worth 57 points. The Answer Key is included in this document.
