To determine Explain why a unit conversion really involves just multiplying by 1. Find the two forms of 1 that apply with the conversion 1 lb = 16oz. Explanation Given Info: 1 lb = 16oz Calculation: Many problems that we encounter everyday involve converting numbers from one unit to another such as from kilometers to meters or kilograms to grams etc. Let’s take a simple example of converting 5 feet to inches. Because 1 foot is equal to 12 inches, we do the conversion as follows: 5 ft = 5 ft × 12 in 1 ft = 60 in Note that in multiplying by 12 in 1 ft , we have just multiplied by 1, because 12 inches and 1 foot are equal. To all unit conversions, which require an appropriate way of multiplying by 1, this idea can be extended, so that the meaning of the original expression is not changed. For example, following are the different ways of writing 1: 1 = 1 1 = 9 9 = 1 hour 60 min = 12 in 1 ft Now, let’s consider an example of converting 112 oz into lb...
