THESE FRACTIONS ARE CALLED: CONVERSION FACTORS

Convert 21.5 inches to cm! cancel units Step 2: Choose a conversion factor which will allow you to cancel units of a given quantity ( inches in our case) 21.5 inches x

10
Convert 21.5 inches to cm! cancel units Step 2: Choose a conversion factor which will allow you to cancel units of a given quantity ( inches in our case) 21.5 inches x cancel and Step 3: Multiply, cancel and check the units 21.5 inches x = 54.61 cm = 54.6 cm
