This document provides a review of customary units, fractions, and dimensional analysis. It includes examples of using conversion factors to find a common denominator between fractions and to convert between units. Dimensional analysis is described as the process of analyzing units to determine which conversion factors to use. Examples are provided of using conversion factors and fraction bars to solve conversion problems between units like inches, feet, quarts, gallons, and yards.

1. Review of Customary Units, Fractions, and Dimensional Analysis. By Ms. Dewey-Hoffman February 23, 2020 Chapter 5, Section 5 (if you must know)

6. This is a Fraction Bar These Bars mean Multipl-ication and separate fractions or Conversion Factors. 10 quarts = ? gallons 10 Quarts ? Gallons Conversion Factor Goes Here 4 Quarts 1 Gallon Now turn it into a Fraction/Multiplication Problem 10  ¼ = 2 ½ gallons 10 quarts = 2 ½ gallons

7. This is a Fraction Bar These Bars mean Multipl-ication and separate fractions or Conversion Factors. Dealing with Mixed Numbers and Conversions? 3 3/16 yards = ? inches 1) Change Mixed Number to an Improper Fraction, then Convert. 51 Yards 1 Yard 3 Feet 1 Foot 12 Inches 16 2) Take the answer and Change to a Mixed Number. Notice how the IMPROPER Fraction looks like a Fraction on the T graph. (51  3  12)  (16  1  1) = 114.75 or 114 ¾
