Setting It up • First numerator is ALWAYS 1 and your LARGEST measurement • First Ratio is your SCALE Example: How many inches are in 7 feet
Stop, Drop, and Watch How many feet are in 3 miles?
It takes two, let’s try together! A book weighs 60 ounces. How many pounds is this?
You try! • 5 ½ gallons = quarts • 4 yards = inches • 13,200 feet = miles 4.7 pints = cups
Use Gallon Man Use Gallon Man to answer the following questions: 1 gal=________________quarts 1 quart=______________pints 1 pint=_______________cups 1 gal=________________cups 1 gal=________________pints
