Final answer:
To simplify 13.75 to a whole number, round it to the nearest whole number, resulting in 14. The concept of rounding and significant figures is important in accurately expressing numbers in mathematics, especially in scientific contexts.
Step-by-step explanation:
The simplified whole number form of 13.75 is not directly provided in the reference information, but the concept of significant figures and rounding can be applied to find the answer. Since the question asks for a simplified whole number, we need to round 13.75 to the nearest whole number. The decimal part .75 is closer to 1 than to 0, which means when rounding to the nearest whole number, 13.75 is rounded up to 14.
Understanding the basics of significant figures is important in mathematics, especially as problems become more complex. For example, if a calculator answer is 921.996 but our significant figure is to the hundredths place, as stated in the reference, then the final answer should be rounded to 922.00 because the thousandths place is a 6, which is greater than 5, tipping the scale to round up.
Lastly, applying the concept of rounding to limits such as three significant figures or to a specific decimal place is a key skill in mathematics. When working with measurements or in scientific contexts, rounding to the correct level of precision is crucial to ensure accurate and reliable results.
