2. Base Number
The term “base number” directly relates to “what is 20 of 68” as the quantity from which a percentage is extracted. In this specific context, 68 functions as the base number. The inquiry “what is 20 of 68” is intrinsically dependent on the existence and value of this base number. Without 68 as the reference point, the question becomes meaningless. The act of calculating twenty percent necessitates a number to which the percentage can be applied. A flawed understanding or misidentification of the base number will invariably lead to an incorrect result. For instance, if one mistakenly uses 86 as the base number, the calculation will yield a value representing twenty percent of 86, not the intended value related to the original problem.
The practical significance of understanding the base number is demonstrable across various scenarios. Consider a situation where a store offers a 20% discount on all items. If an item is priced at $68, the base number is $68. The amount saved represents the discount, calculated from this base. Similarly, imagine a company projecting 20% revenue growth, where their prior year’s revenue was $68 million. The base number is $68 million. Therefore, accurately identifying the base is crucial. In investment contexts, if a portfolio is valued at $68,000 and experiences a 20% loss, the base number is $68,000, directly impacting the calculated loss amount.
In summary, “what is 20 of 68” places paramount importance on the concept of the base number, 68. It is the foundation upon which the percentage calculation rests, and accurate identification is crucial for deriving a valid answer. Misunderstanding this concept has tangible consequences in various fields, ranging from finance and retail to statistical analysis. Recognizing and properly utilizing the base number is an essential step in successfully calculating percentages and interpreting their practical implications.
