LESSON 7 HW QUESTIONS??
LESSON 8: USING UNIT ANALYSIS TO CONVERT MEASURES Unit Analysis : a process for converting measures. Ex: An elephant can charge at speeds of about 25 miles per hour. How fast can an elephant charge in feet per hour?
IN GENERAL.. a)Larger units Smaller units : MULTIPLY b)Smaller units Larger units : DIVIDE
Draw a 1 ft x 1 ft square and label it square A. Draw a 12 in x 12 in square and label it square B.
1.What are the areas of squares A and B? 2.Why is it necessary to multiply the unit ratio twice to convert square feet to square inches?
NOW EXTEND TO 3-DIMENSIONS Draw a cube with dimensions of 1 yard and one with dimensions 3 feet. Use a unit ratio to convert the volume of the first cube into cubic fee.
