Review Questions

• Explain the relationship between hundredths and the decimal number system.
  • Hundredths are an integral part of the decimal number system, representing the second decimal place and a value that is one-hundredth of the whole number. The decimal system allows for the expression of fractional quantities with greater precision than whole numbers by using place value, where each digit to the right of the decimal point represents a power of 10. Hundredths, specifically, represent a value that is 1/100 of the whole, enabling more detailed and accurate numerical representations.
• Describe how hundredths are used in real-world applications.
  • Hundredths are commonly used in a variety of real-world applications where greater precision is required, such as in measurements, financial calculations, and scientific data. For example, in measurements, hundredths can be used to express lengths, volumes, or weights with more accuracy than whole numbers or tenths. In financial contexts, hundredths are used to represent values like prices, interest rates, and exchange rates. In scientific fields, hundredths are often used to record and analyze data with a high degree of precision, such as in measurements of temperature, pressure, or chemical concentrations.
• Analyze the importance of rounding to the nearest hundredth in mathematical and scientific calculations.
  • Rounding decimal values to the nearest hundredth is often crucial in mathematical and scientific calculations to ensure appropriate levels of precision and accuracy. Hundredths provide a balance between overly precise values that may be impractical or misleading, and rounded whole numbers or tenths that may lack the necessary level of detail. By rounding to the nearest hundredth, calculations can be simplified while still retaining a meaningful level of precision, which is essential in fields like engineering, finance, and experimental research. This practice helps to minimize the impact of rounding errors, improve the reliability of results, and facilitate clear communication of numerical information.
