Unit+Rates

= 7-RP1 = =Compute unit rates associated with ratios of fractions, including ratios of lengths, areas, and other quantities measured in like or different units.=

Example:
 * If a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2 over 1/4 miles per hour, equivalently 2 miles per hour.

 * I can compute unit rate.

Skills in this standard Prerequisite skills This standard does not seem to add content to the previous course of study for 7th grade. The example seems to be more rigorous than the questions asked in previous ARMT item specs.
 * My Humble Opinion **
 * 1) Compute unit rates measured in like units
 * 2) Compute unit rates measured in unlike units.
 * 1) Simplify fractions
 * 2) Divide fractions
 * 3) Work with complex fractions
 * 4) Convert units of measurement within the same system
 * 5) Convert units of measurement from one system to another
