Big Fat Fractions Here is a great way to convert from any unit to another….from pounds to kilograms…. Seconds to year… whatev.. 1.Get out a piece of notebook paper! Draw these lines… label them big fat fractions Lets start with an easy conversion example: 20 pounds= _____ kilograms Units you want Units you are given Conversion Factors We want this ________ Kg 20 lbs 1 Kg 2.2 lbs They give us this Here is our given conversion factors We put lbs on the bottom to cancel it Conversion Factor= 1 kg= 2.2 lbs Conversion Factor= 1 kg= 2.2 lbs NEXT PAGE 

________ Kg 20 lbs 1 Kg 2.2 lbs They give us this Here is our given conversion factors We put lbs on the bottom to cancel it The units you want is now left over… but what do we do with the #’s Math Rules 1.If one number is on top and another is on the bottom you divide the numbers 2.If they are both on top you multiply ________ Kg = 20 lbs 2.2 lbs = 9.09 kg Try This: o&feature=related I will log you in.
